Thank you for taking the time to report this bug and helping to make Ubuntu better.
On my test on Vivid, /lib/systemd/system/samba.service exists, is a symlink to /dev/null, and causes "sudo systemctl start samba" to output "Failed to start samba.service: Unit samba.service is masked.". Instead, /etc/init.d/{smbd,nmbd} work directly, and "sudo systemdctl {start|stop} {smbd|nmbd}" both appear to work correctly. On reboot, smbd and nmbd are both started correctly. So it seems that I cannot reproduce, though I haven't tried an upgrade for Utopic. Do you have a previous customised version of /etc/init.d/samba that you have not updated for Vivid? Please provide steps to reproduce, and once done, change the bug status back to New. Thanks! ** Changed in: samba (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478289 Title: samba fails to start at boot after 15.04 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1478289/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
