I dual boot between Linux Mint and Feren OS (I prefer Feren). I just booted up Linux Mint and installed Opera as an exercise. It is quite simple to do. Opera is not in the software manager so you have to do the following. 1/ Go to website "https://www.opera.com/download" and hit the download button (it should automatically detect linux). 2/ In the popup window select "Open with GDebi Package Installer (default)" and click OK. 3/ Wait until it installs, and that's it. Regards Bill.
