[Aptitude-devel] Bug#836263: aptitude: safe-upgrade removes dirmngr and gnupg-l10n

[Sven Joachim]

Package: aptitude
Version: 0.8.3-1
Severity: normal

After a recent upload of gnupg in unstable the following happens: 

,----
| $ LANG=C aptitude -s -V -D safe-upgrade
| Resolving dependencies...                
| The following packages will be REMOVED:
|   dirmngr{u} [2.1.14-5] (R: gnupg)  gnupg-l10n{u} [2.1.14-5] (R: gnupg)  
| The following packages will be upgraded:
|   gpgv [2.1.14-5 -> 2.1.15-2]  
| 1 packages upgraded, 0 newly installed, 2 to remove and 11 not upgraded.
| Need to get 365 kB of archives. After unpacking 5112 kB will be freed.

| Would download/install/remove packages.
`----

Short analysis: both the old (2.1.14-5) and the new (2.1.15-2) version
of gnupg have a strictly versioned Recommends on dirmngr and gnupg-l10n.
The new gnupg version is not installable because it Breaks python-apt,
but dirmngr and gnupg-l10n could be upgraded.  However, their new
versions become unused and so aptitude removes them which is clearly
suboptimal (they should rather be held back to not break the gnupg
Recommends).
