It appears that you installed a version of wine from a ppa repository instead of the version that is available by default in Ubuntu's repositories. For some reason, there is a problem with either that repository or with the way the ppa repository line was entered.
Please go to System > Preferences > Software Sources. Go through the tabs and locate the wine-ppa line and disable it.

Then run...
sudo apt-get update
Did that fix it?
