Comment 15 for bug 154161

Repositories are in Ubuntu a huge server which contains thousands of programs and libraries all disposable to download and install in Ubuntu. Dependencies are all managed by synaptic in this incredible system. It makes installation of programs really easy and avoid incompatibilities or else.

From what I see, it's normal that you doesn't get to install wine because the ubuntu repositories are not activated. The only repositories that are activated are the Wine one, but you'll not be able to install dependencies if the Ubuntu repositories themself aren't enabled. Anyway, you doesn't need to add Wine repositories in order to install Wine because Wine is already in the Ubuntu repositories ( like most of all OS softwares ) so what you need to do is :

1. Open Synaptic and click on Settings / Repositories
2. Go to the Third Party tab and remove everything you find in that section ( except of course if there are some that you want to keep, but I suggest you to delete them all, including all Wine Budgetdedicated repositories )
3. Then go to Ubuntu Software tab and check everything, and click on Close
4. You're now back into Synaptic, and you can click on Reload to reload the list of packages.
5. Remove any Wine version you could have installed before re-installing it through synaptic, everything should work now.
