Opera has been temporarily removed from Software Boutique. https://bitbucket.org/ubuntu-mate/ubuntu-mate-welcome/commits/708a166baec9916386697142a8c3b3630493ea96
The packages have been updated for the upcoming 17.04, but also 16.04 and 16.10 via the PPA (by clicking on "subscribe for updates" within Welcome/Boutique). Once Opera has fixed this issue, we'll be able to feature this application again. ** Changed in: ubuntu-mate Status: Confirmed => Fix Released ** Changed in: ubuntu-mate-welcome (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663523 Title: Adding Opera Browser from Software Boutique breaks apt in Ubuntu Mate 16.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1663523/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
