Problem after upgrade

[DareDevil73]

I recently updated from 18.3 to 19.

Today, after a few days, I got this:

Code: Select all

sudo apt-get dist-upgrade 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Error!
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:
 libglx0 : Depends: libglx-mesa0 but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Asking the version table about the above package I got:

Code: Select all

apt-cache policy libglx-mesa0
libglx-mesa0:
  Installed: (none)
  Candidate: 18.0.5-0ubuntu0~18.04.1
  Version table:
     18.0.5-0ubuntu0~18.04.1 500
        500 http://it-mirrors.evowise.com/ubuntu bionic-updates/main amd64 Packages
     18.0.0~rc5-1ubuntu1 500
        500 http://it-mirrors.evowise.com/ubuntu bionic/main amd64 Packages

I suspect I am in the same trouble. Could you somebody clarify me the situation?

Thank you very much!
Antonio

Maybe your mirrors are not updated yet. Try opening Software Sources and restore the mirrors to default.

[DareDevil73]

Thank you for your answer.

I restored the default repositories and disabled all the additiona PPAs:

But I get still the error:

what does it say if you try:

Code: Select all

sudo apt install libglx-mesa0

and

Code: Select all

apt-mark showhold

Instead apt-mark showhold prints absolutely nothing!

Thank you!!!

Try this one also, I hope this will resolve the broken dependency:

Code: Select all

sudo apt install -f

I am running dry on ideas at the moment, I am sorry. Since this thread has already been marked as solved, maybe it would be better to create an new one to get proper assistance. You could also ask the moderators to move your posts from here to the new one.

libglx-mesa0 : Depends: libglapi-mesa (= 18.0.5-0ubuntu0~18.04.1) but 1:18.0.0-0~x~padoka0 is to be installed

What PPAs have you got active? - Maybe this one? - https://launchpad.net/~paulo-miguel-dia ... untu/pkppa

Get rid and downgrade foreign packages in Software Sources....

Hi, I have no additional PPAs.

What does apt policy libglapi-mesa return?

[DareDevil73]

Return:

libglapi-mesa:

I force the installation by sudo apt-get install libglapi-mesa=18.0.5-0ubuntu0~18.04.1, but it uninstalled marco and xapps.

If I try to issue sudo apt-get install marco zenity libwebkit2gtk-4.0-37 I get:

[Sir Charles]

I am not sure what others will suggest, but do you think backing up your /home (etc. using something like Aptik to do it) and doing a fresh install of
LM 19 could be an option at this point, instead of getting into an spiral of unmet dependencies and trying to resolve them?

[smurphos]

I really do not understand how apt-cache policy & apt-policy can return different outputs.

1:18.0.0-0~x~padoka0 is as far as I can tell the xenial version from that PPA linked.

Can you check in Software Sources in the downgrade foreign packages section for anything listed. If there is go ahead and downgrade.

Other things to try is run an apt autoclean and apt install --reinstall libglapi-mesa.

[DareDevil73]

Sorry, but my system has died, so I had to reinstall it from scratch.

Thank you very very very much to all guys who supported me!
