Installing/updating Maxima and wxMaxima to 5.27 and 12.04, respectively

It had been awhile since I had used wxMaxima/Maxima on my desktop, and I was getting an error when I was trying to run calculations that wxMaxima was not connected to Maxima.  I began to search for a solution then decided to check the version.  A newer version had of course come out for Maxima-xMaxima as 5.27 and wxMaxima as 12.04.  I decide that upgrading would be easier and more logical than trying to fix the old version I had.

First, I removed the old version.  You can probably do this through through SPM, the terminal, or (what I did) USC.  Then add the repository from blahota on launchpad:

https://launchpad.net/~blahota/+archive/wxmaxima/

apt-add-repository ppa:blahota/wxmaxima


I already had this added from an older version upgrade.  Then run update to update the repositories:

sudo apt-get update


Then install wxMaxima and Maxima either through the terminal (not sure of the exact command; probably something like sudo apt-get install maxima or whatever the file name is), USC, or (what I did) through SPM.  I just selected what I wanted to install.

Sage 5.1 - Download for Linux - Ubuntu PPA

Sage - Download for Linux

I just realized that Sage 5.1 is out.  I think I was on 4.7 something on my desktop at home!

Anyways, they now have a ppa for Ubuntu users.  I may have known this, but since I haven't used Sage in awhile I may have forgotten.  I am mainly using Python now.  I will still occasionally use Sage and wxMaxima for backup and to keep up with its development.

apt-add-repository -y ppa:aims/sagemath
apt-get update
apt-get install sagemath-upstream-binary

installation - How do I install the latest 2012 TeX Live on 12.04? - Ask Ubuntu

Ubuntu 12.04 comes with an old 2009 version of TeX Live.  I recently got my Ubuntu desktop back in shape (still not %100 but it's managable. and I was using Kile to compile a LaTeX document which had the bigints package.  This worked fine on my Windows using TeXstudio.  I think because I just recently installed TeX Live and it was the 2011 version.  I could have just placed the .sty file in the appropriate location as a solution.

http://blog.irrepupavel.com/2007/02/installing-latex-style-files-sty-on.html THIS LINK IS DEAD!

SEE post http://timothyandrewbarber.blogspot.com/2012/11/placing-latex-sty-files-in.html for manually installing .sty files instead!

However, I noticed, as I previously mentioned, that the version of TeX Live in Ubuntu 12.04 was outdated.  Ubuntu tends to run behind on some things in its repositories.

To install the latest TeX Live, 2012, I found this:

installation - How do I install the latest 2012 TeX Live on 12.04? - Ask Ubuntu

I ran:

sudo apt-add-repository ppa:texlive-backports/ppa

and then:

sudo apt-get update && sudo apt-get install texlive

I then installed the texlive-full package through synaptic just because I didn't feel like going through and picking the packages I needed, :P.

http://stackoverflow.com/questions/1911713/add-find-style-files-in-to-latex

$ sudo apt-get install texlive-full

It looks like 12.10 should come with the 2012 version of TeX Live.

Sorry the blog is messy.  I've been quite busy.  I also apologize to not replying to some comments.  I just haven't had the time at the moment.  Got some good stuff coming though such as using Asymptote.  I really like it.  It's not too hard and the figures look great.  I am happy so far as it replaces Origin for my needs.

Install XFCE 4.10 In Xubuntu 12.04 Precise Pangolin Via PPA ~ Web Upd8: Ubuntu / Linux blog

Install XFCE 4.10 In Xubuntu 12.04 Precise Pangolin Via PPA ~ Web Upd8: Ubuntu / Linux blog

For those of you interested in XFCE and Xubuntu, the lasted XFCE, version 4.10,  has appeared but did not ship with 12.04.

I was using Xubuntu/XFCE cause my GNOME classic was messed up.

To install:

sudo add-apt-repository ppa:xubuntu-dev/xfce-4.10
sudo apt-get update
sudo apt-get dist-upgrade

If after running "dist-upgrade", you get 3 held back packages which can't be upgraded, open Synaptic Package Manager (it's installed by default in Xubuntu), click the "Mark all upgrades" button, then "Apply". Synaptic will ask to remove one package and install a new one - select yes and you're done.

I didn't have to do this ^^.  Not sure why.

Addition tip given:

To install XFCE 4.10 in Xubuntu 12.04 (if you're using a different desktop environment such as GNOME for example), instead of the last command above, use the following:

sudo apt-get install xubuntu-desktop

Chromium daliy builds PPA

In order to add the Chromium daily builds PPA to your Ubuntu repositories use the terminal and type the command:

sudo apt-add-repository ppa:chromium-daily/ppa

Updating Mendeley Desktop from version 1.1 to 1.3 in Ubuntu 11.10

Alright, so I was having issues updating MD.  I finally figured it out.  Stupid mistake by me.  I posted this in the Mendeley support forum:

I am having trouble upgrading from MD ver 1.1 to 1.3 in Ubuntu 11.10. I've looked everywhere for help but haven't found any. I noticed there (or I couldn't find it at least) is not an MD repository for Ubuntu 11.10. Is it because there (from what I have noticed) are some problems with dpgk and/or dependcies, etc., especially with new installations? I've tried deleting and re-downloading. I've tried running the update in the terminal, in the update manger, and in the software center. So far, nothing works. I don't want to delete and do a fresh install since Mendeley Desktop does not save preferences/settings for "Document Details" (unless there is a way and I do not know/ haven't found it). Any ideas, thoughts?

I answered it myself once I figured it out which wasn't long after I posted it!!

Ahh, what a sec. I may have found my mistake. I tried "sudo dpkg -i mendeleydesktop_1.3_amd64.deb" but didn't realize, until now, that I didn't specify the directory which is in Downloads in my home folder. I also didn't read the error closely which told me the file wasn't found in the directory I was using!! So I changed the directory and reran the command. Oh yeah, that worked! Doh! Sorry. Well if anyone overlooks stuff like me, then maybe this will help!

Just type sudo dpkg -i mendeleydesktop_1.3_amd64.deb in the terminal but make sure you point it to or are in the right directory. I had to do this since the commands sudo apt-get update and sudo apt-get install mendeleydesktop did not work for me. I think it has something to do with MD not having posted a repository for Ubuntu 11.10 yet (?).

Edit: 1-18-12 A new release just came out for MD, 1.3.1.  The update manager automatically installed it this time.

Upgrading to/Installation of Kile 2.1

Ubuntu does not update Kile from 2.1 beta 4 to the latest 2.1 release. In order to update you can do two things.

1) Compile your own like I did with wxMaxima

How to compile Kile for Linux/BSD - http://kile.sourceforge.net/help.php#compile

2) Or find someone that has already compiled a deb package install like I should have looked for one for wxMaxima. (I have found the PPA for wxMaxima here -> Maxima and wxMaxima by István Blahota - https://launchpad.net/~blahota/+archive/wxmaxima as ppa:blahota/wxmaxima and have added it to my original wxMaxima post too.)

In this forum topic, I found a PPA (Personal Package Archive) which once added to the repositories and updated will then install once you run the update manager.

[SOLVED] Kile upgrade - Ubuntu Forums - http://ubuntuforums.org/showthread.php?t=1773808

See here for PPA explanation. I've used it several times without knowing what it was or did. Now I think I understand a little bit better.

How do I use software from a PPA? - https://launchpad.net/+help/soyuz/ppa-sources-list.html

To start installing and using software from a Personal Package Archive, you first need to tell Ubuntu where to find the PPA.

Important: The contents of Personal Package Archives are not checked or monitored. You install software from them at your own risk.

Adding the PPA to Ubuntu 9.10 (Karmic) and later

If you're using the most recent version of Ubuntu (or any version from Ubuntu 9.10 onwards), you can add a PPA to your system with a single line in your terminal.

Step 1: On the PPA's overview page, look for the heading that reads Adding this PPA to your system. Make a note of the PPA's location, which looks like:

ppa:gwibber-daily/ppa

Step 2: Open a terminal and enter:

sudo add-apt-repository ppa:user/ppa-name

Replace ppa:user/ppa-name with the PPA's location that you noted above.

Your system will now fetch the PPA's key. This enables your Ubuntu system to verify that the packages in the PPA have not been interfered with since they were built.

Step 3: Now, as a one-off, you should tell your system to pull down the latest list of software from each archive it knows about, including the PPA you just added:

sudo apt-get update

Now you're ready to start installing software from the PPA!

So in this case do:

sudo add-apt-repository ppa:kile/stable

sudo apt-get update

(launchpad.net link -> Kile - kile stable - https://launchpad.net/~kile/+archive/stable)

Then run the update manager either from the apps (GUI tool - Ubuntu Update Manager) or the terminal in the command line (I don't know the terminal command).

Ah, found it here -> How do I update Ubuntu Linux softwares? - http://www.cyberciti.biz/faq/how-do-i-update-ubuntu-linux-softwares/

sudo apt-get upgrade

From the site:

=> apt-get update : Update is used to resynchronize the package index files from their sources via Internet.

=> apt-get upgrade : Upgrade is used to install the newest versions of all packages currently installed on the system

=> apt-get install package-name : install is followed by one or more packages desired for installation. If package is already installed it will try to update to latest version.

wxMaxima - Community Ubuntu Documentation - Installing the latest version by compiling and PPA

In order to install the latest wxMaxima (a Mathematica type software) by compiling the source code yourself follow these instructions (this is not necessary as you can use the PPA that I provide further below). The Ubuntu SC only installs 0.8.5 while the latest version as of this date is 11.8.0

wxMaxima - Community Ubuntu Documentation

Download the latest version here: http://sourceforge.net/projects/wxmaxima/files/

Uninstall the old version if you have one.

sudo apt-get remove maxima-doc wxmaxima

Then:

You will need the virtual package "build-essential" for making the package and the package "checkinstall" for building a debian package. So if you don't have it or are unsure,

sudo apt-get install build-essential checkinstall

Now its time to extract, configure, make and install your package:

tar xfvz /"locationof"/wxMaxima-"latest-version".tar.gz
sudo apt-get build-dep wxmaxima
cd /"locationof"/wxMaxima-"latest-version"/
./configure --enable-dnd --enable-printing --enable-unicode-glyphs --prefix=/usr --exec-prefix=/usr
make
sudo checkinstall

After

sudo apt-get build-dep wxmaxima

I extracted the .tar.gz file because the /"locationof"/wxMaxima-"latest-version"/ directory didn't exist until you do this. You may be able to do this (extract) earlier. Then follow the rest of the directions:

ay "yes" to create a document package and paste the description of Maxima off of the website pasted bellow:

wxMaxima is a cross platform GUI for the computer algebra system maxima based on wxWidgets.

When this is done type "0" then "ENTER" and enter your email address so that people know who you are if they use your package you@somewhere as an example

hit "ENTER" and hope for the best. Checkinstall attempts to build you a deb package which it automatically installs by default and is also included in the directory you made WxMaxima, i.e. the deb is in /"locationof"/WxMaxima-"latest-version"/. Thus if everything goes smoothly you now have the latest version of wxmaxima installed.

I have found the PPA for wxMaxima here -> Maxima and wxMaxima by István Blahota - https://launchpad.net/~blahota/+archive/wxmaxima as ppa:blahota/wxmaxima.

Thus to install via PPA:

sudo add-apt-repository ppa:blahota/wxmaxima

sudo apt-get update

Then install from USC (Ubuntu Software Center) or if an older version is already installed simply type into the terminal command line:

sudo apt-get upgrade

Links to Maxima and wxMaxima:

Maxima, a Computer Algebra System - http://maxima.sourceforge.net/

Maxima is a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. Maxima can plot functions and data in two and three dimensions.

The Maxima source code can be compiled on many systems, including Windows, Linux, and MacOS X. The source code for all systems and precompiled binaries for Windows and Linux are available at the SourceForge file manager.

Maxima is a descendant of Macsyma, the legendary computer algebra system developed in the late 1960s at the Massachusetts Institute of Technology. It is the only system based on that effort still publicly available and with an active user community, thanks to its open source nature. Macsyma was revolutionary in its day, and many later systems, such as Maple and Mathematica, were inspired by it.

The Maxima branch of Macsyma was maintained by William Schelter from 1982 until he passed away in 2001. In 1998 he obtained permission to release the source code under the GNU General Public License (GPL). It was his efforts and skill which have made the survival of Maxima possible, and we are very grateful to him for volunteering his time and expert knowledge to keep the original DOE Macsyma code alive and well. Since his passing a group of users and developers has formed to bring Maxima to a wider audience.

We are constantly updating Maxima, to fix bugs and improve the code and the documentation. We welcome suggestions and contributions from the community of Maxima users. Most discussion is conducted on the Maxima mailing list.

How to Install/Unistall GNOME 3 on Ubuntu 11.04

Edit:9-24-11 Apparently GNOME 3 runs pretty well in the latest beta versions of 11.10 which GNOME 3 comes with by default, I believe.  Not sure how this is playing out as I thought Unity was the go to for Ubuntu.  The next release is pretty close Oct. 13th for 11.10 if I am correct.

Ah, I found

Unity is based atop of the latest unstable release of GNOME 3.

Ubuntu 11.10 Beta 2 Released, Reviewed - September 22, 2011 - http://www.omgubuntu.co.uk/?p=20709

Ubuntu 11.10 Beta 2 (Oneiric Ocelot) Released - September 23, 2011 - http://www.ubuntugeek.com/ubuntu-11-10-beta-2-oneiric-ocelot-released.html

I'll make a new post about this as well.

---

Edit: 8-23-11

Ok, I really jacked my installation up. I tried to uninstall GNOME 3 and reinstall Ubunt/GNOME 2 with no luck. When I unistalled GNOME and couldn't reinstall it following this:

Follow the below steps to remove gnome 3 and revert to Gnome 2.x.

sudo apt-get remove libgtk-3-common
sudo apt-get install ppa-purge
sudo ppa-purge ppa:gnome3-team/gnome3
sudo apt-get install gnome-panel

Reboot and you should be back to good old classic gnome. In case you don’t find gnome back again. try this.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ubuntu-desktop

from here -> Ubuntu 11.04 : Uninstall Gnome3 and revert to Gnome 2.x - April 26, 2011 - http://www.ajopaul.com/2011/04/26/ubuntu-11-04-uninstall-gnome3-and-revert-to-gnome-2-x/

Didn't work. Of course not anyone's fault but mine. I was receiving some dependency errors or something like that. My linux knowledge is VERY shallow so this didn't help.

Anyways I found a blog note (which I can't find now!) that had an alternate idea.

Ah here it is: Tutorial: How to remove/uninstall Gnome 3 in Ubuntu 11.04 (Natty Narwhal) - 31 May, 2011 - http://supportlife.wordpress.com/2011/05/31/tutorial-how-to-removeuninstall-gnome-3-in-ubuntu-11-04-natty-narwhal/

Have you installed Gnome 3 from ppa:gnome3-team/gnome3 because you were tired of Unity or just because you wanted to test the new shell and this has broken your login? Are you now on the login screen but no graphic environment will ever work?

Then you have to remove gnome 3 following the steps below:

- Press CTRL+ALT+F1 to access the terminal window and log in. At the prompt type following commands:

- sudo apt-get remove libgtk-3-common

- sudo apt-get install ppa-purge

- sudo ppa-purge ppa:gnome3-team/gnome3

- sudo apt-get dist-upgrade

- sudo apt-get install gnome-panel

- sudo shutdown –r now

The pc will reboot and you should be able to use Unity/Classic login again.

Good luck!

It uninstalled Ubuntu/Unity/Gnome classic and then (tried to) reinstalled it. I got to the last step before restarting "sudo apt-get install gnome-panel" and had some dependency issues again.

Unfortunately, I only had Kubuntu and Xubuntu installed now so when I restarted it asked for a DM login which was either KDM or LXDM. I chose KDM thinking nothing of it. I restarted and the KDM came up fine. I noticed I had to enter my username. No biggie, I thought. I also couldn't select GNOME or Ubuntu since it has been uninstalled at this point. I entered what I thought was my username, but it didn't work. Ok, I tried some other variations of what it could be. Didn't work. Great. So I got my laptop out, as this was all occurring on my desktop, and searched for login problems with forget as a keyword too.

I found where this happened to someone before but in another situation (dammit I forgot this too, I'll try to find these missing pieces).

Ah, I found it too!

Can't Log In to Kubuntu? - 3 weeks ago - http://answers.yahoo.com/question/index?qid=20110805135811AAJ0sTO

I am having problems logging in to Kubuntu. I just switched to Kubuntu from within Ubuntu by typcing into the terminal . Then I selected "kdm" then I ran the line . Then . And this is on a machine that dual boots with windows on the other partition. What I want to know is why Kubuntu forgot my log in information, because I thought it was supposed to transfer all my data over (I backed up my files though). Also, how can I log in, or fix this issue. I was using Ubuntu 11.04. Thanks for the help.

The answer was no help to me either:

re-install ubuntu-desktop, do you know how many libs are shared? half were probably meta packages that pulled out way to much. Whenever you do major stuff like that use aptitude, it won't trash your system like apt-get will.

Ok so I had one last card up my sleeve. I saw here -> [SOLVED] How to remove Gnome 3 from Ubuntu 11.04 - April 11th, 2011 - April 17th, 2011 - http://ubuntuforums.org/showthread.php?t=172675

that someone entered a Live CD or USB and reinstalled Ubuntu over there existing one. They claimed everything was fine and were able to keep files/software/etc. still loaded so they advoid a complete, fresh reinstall or install.

I had the exact same problem, and i managed to fix it pretty easily. I loaded up an Ubuntu 11.04 live cd, and chose the upgrade option. (Even though i was already using 11.04) I let it go through the upgrade process, and when it was done, my computer booted up, i chose Ubuntu classic as my desktop environment (because i am not a fan of unity) and it started it normally with all of my programs and files still there with no sign of gnome 3 in sight. I hope this helps.

So I began to reinstall with a USB stick. I then noticed that the user name Ubuntu gave me then was a version I did not think of at the time. I then tried to go back so I could get out of the upgrade reinstall so I could try the new username idea, but the farthest back I could get was the date setup. I couldn't log out either. So I just restart my computer and pulled the stick. Bad idea!! When I did this I got an error that said

Unable to find a medium containing a live file system

and something about

BusyBox - initramfs

So I looked this up where people had problems with this too, but this error was encounted in some similar and some different situations. I found one solution was to type exit a bunch of times, but this did not work for me past the second when I could type. I couldn't reboot at all without this error or even get an install with the USB LiveCD stick.

The final solution was to get my laptop with the burner out and burn a LiveCD. This worked, but I had to install from start :(.

So moral of the story is...DO NOT INSTALL GNOME 3 unless you know what you are doing and/or you are sure you are going to use it. I would wait anyways until the official release before using GNOME 3 with Ubuntu 11.04 and wait even more for someone to tweak a solution for installing GNOME 3 without harming Unity and/or GNOME classic.

One solution would be to try GNOME 3 on another distro such as Fedora or Open Suse. This is what kind of got me into this mess as I wanted to try to load as many options as I could since I have been jumping back and forth between GNOME classic, Kubuntu, and Xubuntu for quad support.

By the way Xubuntu with XFCE seems to be the best stable-wise so far to use quads (haven't used GNOME classic too much. I like Kubuntu, but it runs slow at times). An alternate might be Lubuntu which runs LXDE and is similar to XFCE but "lighter"

My second mistake came from trying to install too many large package changers at once with the MintMenu install AND GNOME 3. From now on I am going to install large ones like these such as Kubuntu and Xubuntu on at a time between restarts.

Thirdly, I got too greedy with options. I wanted as many distros/options/DEs as possible since I am now forced to look around until Unity supports quads. I wanted to do this like the simple Xubuntu/Kubuntu/Lubuntu options without multi-booting or using a VM. Thus, the MintMenu to get a Mint like DE/distro on Ubuntu and the GNOME 3 fiasco. I looked into multi-booting a bunch of distros, but it looks way too complicated. I think I will stick to running them in VMs.

Finally, my last mistake was not ever backing up my system so that I could recover my setup easily. You'll see this all the time, people warning you to backup your setup and this looks/sounds especially easy in Linux/Ubuntu. So from now on, I am going to do that. That way I couldn't have easily recovered my settings without having to do a fresh install :(, :(, :(!!!!

Edit 8-22-11

Well, apparently GNOME 3 is not officially out yet...so this may be why is still seems unstable/buggy.

GNOME be trollin’ – 3.0 delayed (again) to September 2011 - April 1, 2011 - http://www.omgubuntu.co.uk/2011/04/gnome-3-0-delayed-again-to-september-2011/

The new GNOME 3 website goes live - January 19, 2011 - http://www.omgubuntu.co.uk/2011/01/gnome-3-website-goes-live/

GNOME 3 delayed until March 2011 - July 28, 2010 - http://www.omgubuntu.co.uk/2010/07/gnome-3-delayed-until-march-2011/

Also one of the things when installing GNOME 3 is that the font changes in all DEs (I think not 100% sure). Also, my login screen changed a bit, but I am not sure if that is from the GNOME 3 install, the MintMenu install, or just a regular update? For example the session login bar has been moved to the area where you login instead of on a bar at the bottom of the screen. Going to check to see if Unity is ok after GNOME 3 install and unistall. Cross fingers! Oh and my Ubuntu Classic choice is missing from the session drop down menu, but I am sure that can easily be fixed. I hope I didn't mess things up too badly!!

Ok, so it seems Unity works ok. I couldn't test fully cause I had the Quads going. It may look like that I need to reinstall some icons or the such, but like I said I couldn't test it fully since Unity does not work properly with four monitors.

Also if read this:

Reboot and you should be back to good old classic gnome. In case you don’t find gnome back again. try this.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ubuntu-desktop

I thought I saw an alternate command other than

sudo apt-get install ubuntu-desktop

with gnome instead of ubuntu in the command. I'll try to refind it.

How do I install the latest version of GNOME 3? - Jan 23 at 21:16 - May 19 at 21:56 - http://askubuntu.com/questions/22946/how-do-i-install-the-latest-version-of-gnome-3

Interesting quote explaining some more about the install and other things such as warnings:

Note: GNOME3 is provided as a tech preview for 11.04, it is not officially supported by the Ubuntu team. Here's another warning before you try this.

Using GNOME3 on 11.04 will upgrade major parts of the desktop infrastructure, if you are not familiar with how to do package management then we recommend you try this on a virtualized installation or a non-production system, reverting back to vanilla 11.04 is not trivial.

Specifically GNOME3 will migrate your application settings to gsettings, so if you want to try to rollback you'll get your old settings from before you upgraded.

As with all major desktop upgrades we recommend backing up your important data before getting started.

Some articles on installing GNOME 3 on Ubuntu 11.04. The past few days I have been experimenting with other DEs such as Kubuntu, Xubuntu, and Lubuntu based on KDE, XFCE, and LXDE respectfully. So far I like Kubuntu the best since it is BLUE (I know), I run a lot of KDE apps already (Kopete, Kile, etc.), and the interface is pretty snazzy. However, it may just be me, but Kubuntu runs rather slowly at times. I am running these other DEs since Quad monitors are not "officially" supported in Unity (at least I haven't found a way to run 4 in Unity). I could also throw the Ubuntu Classic or GNOME 2 in there, but I haven't used it much.

Anyways, some info on installing and un-installing GNOME 3. Caveat: apparently GNOME 3 might break Unity so be careful and do your research. For example here is a warning from a commenter on Ubuntu Geek:

Ed says:
July 29, 2011 at 8:12 am

WARNING: gnome3 breaks unity. Even when doing the “ppa-purge” thing … unity might be unable to save any settings afterwards.

Only install gnome3 when you are absolutely sure that you dont need unity any more. Or when you are willing to do a fresh install afterwards.

People have installed it with no problems. GNOME 3 is already the DE for Open Suse and Fedora 15.

Edit: 8-22-11

For me GNOME 3 did not work. The desktop started to show (purplish background and the activity bar), but I couldn't do anything. Luckily I could CTL + ATL + DEL to log out. I think I am going to uninstall it. Plus you can't use GNOME 2/Ubuntu Classic anymore. I think I'll wait until GNOME 3 is more developed to work with other DE installations and when someone has found a way to keep GNOME 2. There may already be a way, I just haven't found it yet.
