[Gnumed-devel] Problem on Debian updating gnumed-common

[Jim Busser]

Even though I did
        apt-get clean
        apt-get update

When I try to apt-get install gnumed-client I get

> The following packages have unmet dependencies:
>   gnumed-client: Depends: python-support (>= 0.90.0) but 0.8.4 is  
> to be installed
>                  Depends: gnumed-common (= 0.4.5-1) but 0.3.10-1 is  
> to be installed
> E: Broken packages


Similarly (for GUI users) the GNOME Update Manager panel advises that  
my Debian virtual system is up to date except that it displays gnumed- 
common in a grayed-out (non-selectable) manner listing

        From version 0.3.10-1 to 0.4.5-1

My /etc/apt/preferences is as follows and sources.list is below that.

Does a putative cause exist for the breakage or ought I regard it  
something that "just happens" on user machines?

Do I need to
        apt-get install gnumed-client -o DPkg::options::="--force-overwrite"
or
        apt-get install gnumed-common -o DPkg::options::="--force-overwrite"
