Although I couldn't reproduce it in a VM, this reliably happens on both of my hardware installs, an old Thinkpad and an Asus Z87-based desktop. The recovery shell is completely unusable. Luckily Ctrl+Alt+Del still reboots the system cleanly.
The workaround seems to be to boot directly to the systemd rescue (or emergency) target, instead of recovery. This can be done simply by adding "rescue" or "emergency" to the default linux command line. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1662137 Title: 16.04 recovery shell works only for two minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1662137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
