Bug#35141: APT does not notice a failing unmount

[Torsten Landschoff <t.landschoff@gmx.net>]

Package: apt

Hi again, 

I just tried to install something from cd but apt was not even able to unmount
the cd-rom. Of course it was my fault but apt did not notice - this might be
to hard for a beginner ;)

Patch included:
