I've tried to install skype in ubuntu 12.04 like this:
After the first step thinks have taken a turn for the worse however. At the moment I can't open the software centre any more. I have an error message in the top right of task bar that reads:
An error occurred, Please run Package Manager from the right-click menu or apt-get in a terminal to see what's wrong. The error message was: 'Error: Opening the cache (E: Malformed line 56 in source list /etc/apt/sources.list (dist parse), E:The list of sources could not be read., E:The package list or status file could not be parsed or opened.)'. This usually means that your installed packages have unmet dependencies
line 56 in the sources.list file now reads:
deb http://archive.canonical.com/ partner
what am I missing here?
