It seems you did have a PPA in use at one point. The unofficial packages are what's causing the upgrade to fail.
'http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu/ maverick/main amd64 Packages 2.4.21-1ubuntu2.1 0 500 '
This needs to be removed along with its packages. Consider using the tool 'ppa-purge' to do this. (You may need to install it.) The proper use of the command would be:
sudo ppa-purge ppa:ubuntu-x-swat/x-updates --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad
