Comment 58 for bug 831768

I haven’t tried the new resolver yet, but the display of :arch qualifiers on foreign packages is a massive improvement.

It’s still missing in a few places though, like the “Provided by” line for virtual packages:

$ aptitude show ia32-libs-multiarch
No current or candidate version found for ia32-libs-multiarch
Package: ia32-libs-multiarch
State: not a real package
Provided by: ia32-libs-multiarch

And packages are listed twice in Conflicts/Breaks/Replaces without :arch qualifiers:

$ aptitude show wine1.4
…
Conflicts: wine1.0, wine1.0, wine1.4
Breaks: ttf-symbol-replacement, ttf-symbol-replacement,
        ttf-symbol-replacement-wine1.3, ttf-symbol-replacement-wine1.3,
        ttf-tahoma-replacement (< 1.3), ttf-tahoma-replacement (< 1.3), wine (<
        1.2.1), wine (< 1.2.1), wine1.2 (< 1.4-0ubuntu1), wine1.2 (<
        1.4-0ubuntu1), wine1.3 (< 1.4-0ubuntu1), wine1.3 (< 1.4-0ubuntu1)
Replaces: ttf-symbol-replacement, ttf-symbol-replacement,
          ttf-symbol-replacement-wine1.3, ttf-symbol-replacement-wine1.3,
          ttf-tahoma-replacement, ttf-tahoma-replacement, wine, wine, wine1.0,
          wine1.0, wine1.2, wine1.2, wine1.3, wine1.3

Same thing in the GUI:

i A --\ wine1.4 1.4-0ubuntu1 1.4-0ubuntu4
