[Aptitude-devel] Bug#672340: aptitude: Dependency solver always uninstalls all foreign-architecture packages

[Ralf Jung]

Package: aptitude
Version: 0.6.7-1
Severity: normal

Dear Maintainer,

the dependency solver of aptitude always wants to uninstall all froeign-
architecture packages I have installed, even if they got nothing to do
with the dependency problem at hand.

I added i386 as foreign architecture to my amd64 system, and installed some
i386 libraries (libc6, libxslt, a few more). When I now install a package
which breaks an installed one, aptitude always suggests to uninstall all
foreign-architecture packages.
For example:
* I installed apache2, which automaticaly selected apache2-mpm-worker
* After installation, I selected apache2-mpm-prfork for installation.
Now apache2-mpm-worker is naturally marked as broken, and usually, the
solution displayed with "e" is to uninstall apache2-mpm-worker (I don't
have anything explicitly depending on it installed).
In this case however, aptitude suggests to also remove all :i386 packages,
for no appearant reason.

Kind regards,
Ralf
