[Aptitude-devel] Bug#878416: aptitude still doesn't do good conflict resolution

Fri Oct 13 13:19:45 UTC 2017

Package: aptitude
Version: 0.8.9-1
Severity: normal

Dear Maintainer,
I have been trying to install libegl-mesa0 libegl1 libglvnd0 and
upgrade libgbm1 but without any success -

[$] sudo aptitude install libegl-mesa0=17.2.2-1 libgbm1=17.2.2-1
libegl1=0.2.999+git20170802-5 libglvnd0=0.2.999+git20170802-5
The following NEW packages will be installed:
  libegl-mesa0 libegl1{b} libglvnd0{b}
The following packages will be upgraded:
  libgbm1
1 packages upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
Need to get 261 kB of archives. After unpacking 1,042 kB will be used.
The following packages have unmet dependencies:
 libegl1 : Breaks: libegl1-mesa (< 17.2.0~rc4-1) but 13.0.6-1+b2 is installed
 libegl1-mesa : Depends: libgbm1 (= 13.0.6-1+b2) but 17.2.2-1 is to be installed
open: 255; closed: 6646; defer: 10; conflict: 42

 The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     libegl-mesa0 [Not Installed]
2)     libegl1 [Not Installed]
3)     libgbm1 [13.0.6-1+b2 (now, testing)]

Accept this solution? [Y/n/q/?] n
open: 652; closed: 44149; defer: 85; conflict: 196

I can understand if the package is uninstallable or something but the
amount of time it takes to give an alternative solution is a bit too
much. It has happened with this upgrade as well as other upgrades as
well. I am at a sort of loss to understand how to navigate this.
