Zypper tries to deinstall everything except a few packages. I think this is a solver bug.

No, it's the price to install acroread with that repos :)

The zypper maintainer decided that --force-resolution is a good default, so you always see the direct consequences of your action. If you had used --no-force-resolution, you would have seen something along this:

package acroread-8.1.2-22.i586 requires libcurl.so.4, but none of the providers can be installed
Comment 3 Michael Schröder 2008-04-22 07:20:02 UTC 
(Btw, the real problem is the missing libcares2-32bit, which makes it impossible to install libcurl4-32bit)
Comment 4 Michael Matz 2008-04-22 13:53:27 UTC 
It would probably be nice of zypper, that, if the solution involves removing
more than (say) 50% of the packages, that it reruns the solver with
forceresolution being off.

I agree :O)
