[wellylug] /usr/bin/dpkg returns error code (1)

[Adam Bogacki]

Hi,

    for the last two or three weeks I have been getting the following 
error messages,
making it impossible to upgrade or dist-upgrade in a mixed etch/unstable 
system .. unless
I use '-f'. After some IRC discussion it was suggested that I have some 
broken cvs pkgs
interfering with apt. I've deleted them but found them automatically 
being reinstalled
and the problem repeating itself.

    I did not manage to show all the error msgs during the IRC session 
so I have posted then below
for an independent opinion in the hope that someone can diagnose the 
problem and suggest a fix.
