I have a hunch that this bug only occurs on systems upgraded from a previous Ubuntu version, perhaps with replacement of upstart with systemd, but not on fresh Ubuntu 15.04 or 15.10 installations. Everyone who is affected: is there anyone who started having this problem on a fresh 15.04 or later installation? Please let us know within a week. This may shed insight onto how this bug may be reproduced.
I've changed status to 'Confirmed' since it looks like all the information that could be provided has been provided. Developers and enthusiasts: if there is anything else we can do to help diagnose this, please let us know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464917 Title: reboot hangs at 'Reached target Shutdown' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1464917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
