[Aptitude-devel] Bug#822331: "E: Cannot remove aptitude within aptitude" on multi-arch

[Christian Klein]

Package: aptitude
Version: 0.8-1
Severity: normal

>From time to time, I invoke a "purge" (_ key) on the "Not Installed Packages"
section in aptitude to remove any config data for packages that were removed
but not purged.
With aptitude in unstable, this gives an error "E: Cannot remove aptitude
within aptitude". With aptitude in testing (0.7.5-3), this is not the case.

I guess this is triggered by the fact that I have multi-arch configured to use
i386 and amd64 packages, and the "Not Installed Packages" section contains the
aptitude:i386 package (which, however, is obviously uninstalled, as I use the
aptitude:amd64 package).
