Which part specifically is giving that issue? Did you replace the sources.list as instructed? Are you running the commands as root?
It does it all the time now when running apt. I replaced all the sources and besides this error it seems to work. (still seeing the mousecursor though). Only this error is annoying because it shows on everything that gets installed.
