Q:

What happened to the opera-next package?

A week ago I noticed opera-next package in New in repository Synaptics' filter. So I installed it to test some HTML. Today I noticed that it has replaced x-www-browser alternative and tried to reproduce it but it was no longer in the repository. I don't remember enabling/disabling PPAs so it could be from official partner repository. And now it's gone. Was there some announcement about why was it removed?

A:

opera-next was never an Ubuntu package. You got it from http://deb.opera.com
(FWIW, the partner repository isn't part of Ubuntu, either, it's an add-on repository from Canonical, that doesn't obey Ubuntu's rules)
