I have tried with 2 PC (one with 2 network cards, the other with only one) and I have the same problem on both PC. My network configuration is with a static IP address, without internet connection.
When I try typing
aptitude install pluto-dcerouter, the same error message appears.
When I try typing
aptitude -y -f install pluto-website-admin, I have a similar error but with the depends pluto-updatemedia
Finally when I try typing
aptitude -y -f install pluto-updatemedia, I have a similar error but with the depends libid3-3.8.3 (which is a virtual package
!!!)
And the following files exist on the hard drive (in directory /usr/pluto/deb-cache/dists/sarge/main/binary-i386)
libidl0_0.8.5-1_i386.deb
libid3tag0_0.15.1b-4.1_386.deb
