[Aptitude-devel] Bug#966488: aptitude corrupts package install selection after dpkg error

[Vincent Lefevre]

Package: aptitude
Version: 0.8.13-1+b1
Severity: grave
Justification: causes non-serious data loss

An upgrade with aptitude failed due to a dpkg lock error (bug 933335).
Then I noticed that not all packages were upgraded, so that I started
aptitude again to complete the upgrade. I typed 'g', but got:

[1(1)/...] Actions: no changes
e: Examine  !: Apply  .: Next  ,: Previous

and 'e' gives:

  --\ Leave the following recommendations unresolved:                           
    lcov recommends libgd-gd2-perl

Since lcov recommends libgd-gd2-perl, this means that it was in
the package install selection before the initial upgrade (note
that I didn't have such a warning in the initial upgrade). But
now libgd-gd2-perl is no longer proposed for installation!
