I recently installed Pear OS 8 and have ran into many problems since. Essentially, I can't download or install anything. At first I was getting a "failed to download repository information" error. I tried sudo apt-get clean and sudo apt-get update commands neither of which worked. After doing more research and trying other commands (I don't even remember what all I tried now), the install button in software center disappeared. I researched this and found out that my download from server was "server from france". I tried to change this both to United states and main server to fix the problem (also running sudo apt-get update command after both of those changes) and nothing is working still.
