I'm completely as a loss as to how to get rid of all Opera packages.
I have ppa-purge installed, but don't know what to specify for the ppa.. I have tried the following:
sudo ppa-purge deb.opera.com sudo ppa-purge deb.opera.com/opera sudo ppa-purge deb.opera.com/opera stable sudo ppa-purge opera-list sudo ppa-purge -p http://deb.opera.com/opera stable
..and many other combinations of the above, and all result in something like:
Warning: Could not find package list for PPA: stable http://deb.opera.com/opera/
This seems a lot harder than it could be to just uninstall (and completely remove) an application. Ideally I'd open the software center, remove Opera and then it could ask me 'also remove the repository?' and then it'd be gone.
