APT busted (libxv1 holding up any install)

[Markus]

I'm still confused about why dpkg complained about the missing file in /var/cache/apt/archives, could you post the output of: ll /var/cache/apt/archives/libxv*

What I meant with the apt-cache policy and show was that you can check from the depends line which packages libdc0 libxv1 need, and then do a check with apt-cache policy on all of them to see if they are installed and try to install them first.

[UPDATE] this cleared up the libxv1 problem:
# dpkg --install --force-overwrite /var/cache/apt/archives/libxv1_4.3.0.dfsg.1-1_i386.deb
[/UPDATE]

I got the same thing when I tried to update xawtv and that required libxv1 to be updated too. Here's a similar "apt-get -t unstable install libxv1" error tree:

the file `/usr/X11R6/lib/libXv.so.1.0' was even removed and the same error showed up.....
