[Bug 829138] Re: passing already installed package to software-center causes conflict message

[Alexey Feldgendler]

Internally, python-apt uses libapt-pkg, which for each package that has
neither "Architecture: all" nor "MultiArch: same" properties generates a
synthetic confclit with its own versions for other architectures. I.e.
gnome-shell for amd64 conflicts with gnome-shell for i386, and vice
versa, which makes sense.

However, python-apt fails to take architecture-specific conflicts (such
as gnome-shell for amd64 conflicting with gnome-shell for i386) into
account, and instead interprets them as plain conflicts of a package
with itself.

I believe the attached python-apt.fix2.patch is a superficial fix that
doesn't fix the real problem but happens to fix its symptom. I'll make
another fix.

Title:
  passing already installed package to software-center causes conflict
  message

Status in “python-apt” package in Ubuntu:
  Confirmed

Bug description:
  in testing the fix to Bug #824692, I noticed that software-center does
  not appear to handle the situation where you pass it .deb file that is
  already installed correctly.

  say you have package-vX.deb which has already been installed on the
  system.

  and you now run 'software-center package-vX.deb' and when it loads up
  you get this message

  "Breaks existing package 'package-vX' conflict: package-vX ( )"

  Now I would expect that running the above command in this case should
  land you on the same page that you get if you navigate through the
  'installed software' pages to that package.
