I would be interested to see if the problem persists in Ubuntu 17.10 or 18.04 (due for release this month).
17.10.1 release: https://www.ubuntu.com/download/desktop 18.04 pre-release: http://cdimages.ubuntu.com/daily-live/current/ That is likely faster than trying to figure out what component, and if any fix for this issue has been made since 16.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761663 Title: Attached encrypted USB drive gets stuck in password prompt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1761663/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
