When booting up Ubuntu 16.04, I'm getting this:

Press enter for maintenance( or type Control-D to continue)

and when pressing enter, I get this error:

sulogin cannot read /dev/tty1 permission denied

Make sure your /etc/fstab is all correct and reboot. I would recommend commenting out all lines except the essential ones (by putting # at the beginning of the line) and trying to reboot. If it works, try uncommenting the lines one by one and rebooting between each try to see which lines is the problem.

  • Thanks. This was a good hint. In my case, it was a mount entry in fstab that referred to an external HDD. It appears that if that drive was in power-save mode while the computer rebooted it did not connect (over USB connection) and this caused the boot process to fail. My solution was to add the option noauto to the respective entry in fstab (this required, of course, taking care of mounting the external drive manually as it was not mounted automatically anymore - but at least it did not prevent the machine from booting). – ElazarR Oct 30 '17 at 7:54

    How would one edit /etc/fstab if they cannot get past the password prompt at boot? – Luke Griffiths May 17 '18 at 0:36
