Installing different versions of debian package

[Lee Hanxue <hanxue@gawab.com>]

Hi,


This may sound stupid, but is it possible to install different versions of a debian package at the same time?

I asked this question because I had some dependencies problem previously. I upgraded a package that caused kdelibs to be upgraded from kdelib 3.1 to kdelibs 3.2. After some time, I wanted to upgrade another package, but apt-get complains that it depends on kdelib 3.1 but kdelib 3.1 is nowhere to be found. 

I tried using --force, and in some instances it does not work. At one point, even kdm would not started. Finally I ended up removing kde and all its dependant packages and reinstalling the latest version from scratch.

What if the different versions of the same package provides different files? For example, libcustom-1.1 provides libcustom-1.1.so and libcustom-1.2 provides libcustom-1.2.so Is it still possible to have both versions to be installed at the same time?

Finally, are there any tools which can track what files are installed from source?


Thank you.
