The package it's complaining about is already installed. I've done a "apt-get -f install" and "dpkg --configure -a" but it doesn't change anything. I've uninstalled and reinstalled the dependencies. I've also run "apt-get install --reinstall". I've removed all of the packages in the output (the one I'm installing, the other packages that have dependencies, and the dependencies themselves) with "dpkg -r --force-depends" and then installed every, again, from the same command-line. When I do an install of the packages it asserts aren't installed, nothing is done. Sometimes Apt thinks they're there and sometimes it doesn't.
Am I overlooking something, or is something going on?
