I had some trouble with the download (slow connection), so it might just be a coincidence that I tapped as the restart dialog appeared. The download was stuck at 100% for a while seemingly doing nothing, and that was when I searched askubuntu and found an article that I interpreted as saying that I should tap the progress bar.
The article on askubuntu is this one: https://askubuntu.com/questions/761631/upgrade-bq- aquaris-m10-from-15-04-to-16-04/766535#766535 I read the grey quote box as if it said I should tap the progress bar, but when reading it again now, I see that I might have misinterpreted it in the heat of the moment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1598433 Title: Unintuitive user interface for OTA upgrades To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-system-settings/+bug/1598433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
