Opera is no longer in the non-oss repository. Would be great if someone could package it.

If there is no official Opera provided package for your Linux distribution of choice, there are various alternative options that will allow you to install Opera. First and foremost, you should check if your distribution offers recent versions of Opera (version 26 and above). If they do not offer it, you may wish to ask them to consider it. Opera's license allows it to be repackaged and distributed directly on Linux. A copy of this license is included in our official .deb package. Please refer to it for more details.
