So this is a multi-tiered problem.
I was trying to play a game via Wine. Series of errors. Okay. Working through them with my rudimentary understanding of script thanks to these forums. Trying to completely uninstall extant Wine in order to install current stable launch (1.4). This seemed to prescribe updating to a newer version of Ubuntu, currently using 10.04 Lucid Lynx. According to official Ubuntu site I need upgrade to 11.10 Oneiric Ocelot. Site indicates opening "Software Sources."
When I open Software Sources either via System> Administration... or via Ubuntu Software Center> Edit the pointer changes to "clock" and the task bar adds appropriate tab but after about 30 seconds both change back and nothing happens.
More forum questing. Similar problems found for Karmic Koala (the version I started with) but inspection of Ubuntu.info file did not seem to confirm bug. Which is just as well because I can't edit the file anyway.
1. How do I fix Software Sources so as to upgrade to 12.04?
2. If I need to edit Ubuntu.info how do I edit the file?
3. Is it possible to fix questviewer.exe error in Wine?
Game still doesn't work but that is lesser problem.
