Unable to install Octave

Question

I am trying to install Octave by using these commands:

sudo apt-add-repository ppa:octave/stable
sudo apt-get update
sudo apt-get install octave

But I am getting the following error message:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 octave : Depends: libosmesa6 (>= 6.5.2-1) but it is not going to be installed or
                   libgl1-mesa-glide3 but it is not installable
E: Unable to correct problems, you have held broken packages.

How do I fix this problem?

[Edit] your question and add the output of apt-cache policy libosmesa6 — A.B., Sep 06 '15 at 12:28
Start the command sudo apt-get install libgl1-mesa-glide3 and add the output into your question. — A.B., Sep 06 '15 at 12:33
@A.B. I have added the output in my question. Please have a look. Also, I would like to tell you I somehow installed libosmesa6 but when I restarted my system, it started giving a blank screen. I ended up doing a fresh install of ubuntu. I later on read this mesa installation creates problems — Noober, Sep 06 '15 at 12:34
@A.B. This is similar to what happened with me earlier- http://askubuntu.com/questions/299543/after-installing-mesa-ubuntu-doesnt-start-up — Noober, Sep 06 '15 at 12:35

This is no universal answer. The problem was complex and was dissolved by a longer analysis in the chat.

Here is a summary from the chat.

sudo apt-get install libosmesa6
sudo apt-get install libglapi-mesa

It removed a lot of packages, eg ubuntu-desktop

sudo apt-get install -f
sudo apt-get install ubuntu-desktop

From here, we used aptitude, a better problem resolver

sudo aptitude install libgl1-mesa-dri

Now a lot of packages was removed, but ubuntu-desktop is installed.

sudo aptitude install unity8
sudo aptitude install octave

Done

The following worked for me at the end on a Ubuntu 14.04 64-bit machine.

In terminal, install:

sudo apt-get build-dep octave
sudo apt-get install libqt4-opengl-dev

Then download and build Octave from source:

wget ftp://ftp.gnu.org/gnu/octave/octave-4.0.0.tar.xz
tar -xaf octave-4.0.0.tar.xz
cd octave-4.0.0
./configure
make
sudo make install

This worked on all the machines I tried in my laboratory.

Yes, So nice. Not one machine. On many machines now ! – naveen chandra Kumar Sep 06 '15 at 11:51
I cannot get the GUI to work. After installing from source what did u do to get the GUI to work? – Noober Sep 06 '15 at 12:22
(i) cd octave-4.0.0 (ii) ./run-octave. I am doing only the above steps and nothing else. – naveen chandra Kumar Sep 07 '15 at 03:22

note that this will use more space and that installing only what is in the dependency error is usually more productive – David Sep 06 '15 at 04:45

@David cole I tried your command and error : The following packages have unmet dependencies: libosmesa6 : Depends: libglapi-mesa (= 10.1.3-0ubuntu0.4)E: Unable to correct problems, you have held broken packages. – Ravan Sep 06 '15 at 04:49
It means instead of adding each dependency it is better to have all dependencies,@DavidCole – Ravan Sep 06 '15 at 04:50

-1 One doesn't need the build dependencies of a package to run the software of the binary package. – David Foerster Sep 06 '15 at 08:22
