Bump! Bump! I've been working on updating several different systems from Meops 3.3.2 test 03 for a few weeks now.
I've found everything aside from this a2ps thing easy to fix. The ndiswrapper package can be uninstalled and re-installed and no longer cause a problem with apt (though I find it doesn't work as well - it's probably better to build from CVS anyway). I swear I tried removing and re-installing a2ps and emacsen-common before - but it didn't work. So on a fresh install I tried what mos suggested and, I too received different errors:
Preparing to replace a2ps 1:4.13b-4.3 (using .../a2ps_1%3a4.13b-5_i386.deb) ...

dpkg: error processing a2ps (--configure):

Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)
Following Nix_Hard's advice, as root I removed and reinstalled the affected packages:
#apt-get remove a2ps
#apt-get remove emacsen-common
#apt-get install a2ps apsfilter
#apt-get install emacsen-common
Everything seems to be working! thanks!
