Cannot install Octave (Dependency problem)

Question

I've tried to install Octave in my Ubuntu 16.04 LTS 64bit using

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

and it generate a dependency problem

the following packages have unmet dependencies:
libosmesa6 : Depends: libosmesa6 (>= 10.2~) but 17.0.70ubuntu0.16.04.1 is to be installed

and when I tried to install libomesa6 it says that it need libglapi

libosmesa6 : Depends: libglapi-mesa (= 11.2.0-1ubuntu2) but 17.0.70ubuntu0.16.04.1 is to be installed

Then I used apt to install libglapi-mesa and I get a message saying it's already up to date

libglapi-mesa is already the newest version (17.0.7-0ubuntu0.16.04.1)

I've tried the solution

but it seems that I already have 'main server' selected

libosmesa6 : Depends: libglapi-mesa (= 11.2.0-1ubuntu2)

It wants an older version of libglapi-mesa. Since you installed the ppa I assume you are getting the newest version of Octave. Thus to install it you will need to downgrade libglapi-mesa.

Note: This may cause issues with other programs that depend on libglapi-mesa.

I have octave 4.0.0-3ubuntu9.1 in 16.04 LTS. It is installed from the standard repository 'universe' without any conflicts. So I suggest that you purge your version of octave, remove the PPA and try to install octave the standard way.

sudo apt purge octave
sudo add-apt-repository --remove ppa:octave/stable

sudo add-apt-repository universe  # maybe/maybe not necessary
sudo apt update
sudo apt install octave

You will probably get an older version of octave than from the PPA, but it is tested with Ubuntu, and I hope it has enough features for you.

Have you got some other PPA, that causes the conflict with the library? -- What happens after you run sudo apt-get install -f – sudodus Dec 14 '17 at 12:06
It gives the same message the same problem – Iduoad Dec 14 '17 at 12:10
Have you got some other PPA, that causes the conflict with the library? Or have you installed some other program package via a non-standard method? – sudodus Dec 14 '17 at 12:12
By the way, I have libglapi-mesa 17.0.7-0ubuntu0.16.04.2 installed in my system. – sudodus Dec 14 '17 at 12:16
I don't remember. I had nearly the same problem with mysql server installation. I don't remember I did solve it – Iduoad Dec 14 '17 at 12:16
Maybe There is a PPA causing the problem. How can I know it it's a PPA problem – Iduoad Dec 14 '17 at 12:18
You can remove the program package, that depends on that PPA, and then remove that PPA and try again to install octave – sudodus Dec 14 '17 at 12:19

I've solved the problem by adding xorg-edgers repository containing the latest version of mesa. I think that libosmesa6 in my main server was obsolete and depended on an older libglapi-mesa package.

sudo add-apt-repository ppa:xorg-edgers/ppa 
sudo apt-get update
sudo apt-get install <package name>
