The official documentation page to install opera says to add this:

deb http://deb.opera.com/opera/ stable non-free

Somehow this:


ended up in the url field of the edit source dialog box. It ended up there from a previous unsuccessful attempt (epic fail - I destroyed updater, software center, and synaptic). The words stable and non-free are in other fields: stable is in 'distribution', i will change that to raring so that it looks like the official ubuntu documentation page. non-free is in 'components'.

So what should be in the url field?

I will change distro to raring.

Is non-free ok to be in component?

4theye - i will try - I don't know how:

software center - add / edit source

hope that woked.

  • That should be fine. Now, do sudo apt-get update from a terminal. May 5, 2013 at 14:24
  • That did it. It showed up in software center.
