[Aptitude-devel] Bug#742708: aptitude confused about to-be-installed version

[Ralf Jung]

Package: aptitude
Version: 0.6.10-1
Severity: normal

Dear Maintainer,

when there are several versions of a package available, aptitude seems to be
confused when I ask it to install a specific version.

Steps to reproduce:
* I have testing, unstable and experimental in my sources (you can find the pinning below,
  as attached by reportbug).
* In aptitude, select "qtcreator" and scroll down to the list of versions
* Currently, I have 3.0.1+dfsg-1 from testing installed. Select 3.0.1+dfsg+exp-2
  from experimental and hit "+".
Actual behaviour:
* The line with the old version (from testing) becomes green, nothing else changes.
* Hitting "g" shows that it wants to install version 3.0.1+dfsg-1 of qtcreator again,
* Hitting "g" again does nothing.
* When aptitude comes back, it seems to notice that I selected version
  3.0.1+dfsg+exp-2 for installation, and correctly marks qtcreator as broken.
Alternatively:
* Immediately after selecting the version from experimental, hit "Q" to quit.
  Then start aptitude again. Now it correctly display qtcreator as broken.
Expected behaviour:
* aptitude should immediately mark 3.0.1+dfsg+exp-2 as to-be-installed version,
  and mark qtcreator broken.

Interestingly, this issue does not affect all packages. For example, qtcreator-doc works
fine, but network-manager is broken. The only pattern I found so far (as weird as this may
sound) is that ony packages where I have to scroll down (I always do that using PgDown)
to get to the list of versions. But that's probably just coincidence.

Kind regards
Ralf
