It seems that you have unofficial PPAs added to your system.
You can open Software Center and search "Software sources" from menus.
Then you can disable unofficial repositories and then upgrade should work.

I use GPG/INLINE, because some mailing list programs modify the headers
of messages and this way make signature.asc files (PGP/MIME)
unverifiable. Please remove lines about beginning and ending GPG
signature blocks in your replies to messages, which are sent by me.
