The later is the easiest case - just stop and notify the user about
this fact.

The question is useless - you can only upgrade to the version which
is contained in the package

In principle this was my initial intention to do (more or less).
It's just a lack of time which prevents me from doing this.

All the tasks above can be solved using debconf (in principle).
I decided that it helps our users if there is a simpler gnumed-server
package sitting in experimental which does not yet contain all this
code for the time beeing.

Kind regards
