Interesting that the deb package manager will install using the -t flag even though the repo does not exist online as we both looked at and saw. Hopefully the apt team can figure a solution out in checking the repo before installing the package. It also might be bad then I can't install vlc so a catch 22.
Installing libcss using the debian package seemed to work. I may look at adding the repo depending as it looks like it requires less install of packages.
