I'm not sure how to solve this problem as both 15.04 and 15.10 with systemd get me only to an emergency shell whereas upstart works just fine. Having struggled with this for a whole version, help would be appreciated.

Here the last few lines of my dmesg:

  • Is plymouth crashing? What does systemctl --failed say? – bain Jan 16 '16 at 03:30
  • I'll check on Monday. But let's say this is the issue how would I circumvent it? – Filicado Jan 16 '16 at 16:26
  • I'd guess it would be a systemd configuration issue. Was this a system that was upgraded from an earlier version of Ubuntu? If so, the quickest way to fix it may be to just install a fresh version of 15.10. Otherwise you'd need to figure out exactly how your config differs from a working install. – bain Jan 16 '16 at 17:10
  • It was a fresh install for 15.04 but systemd never worked on this machine, I always had to fall back to upstart from day 1. – Filicado Jan 16 '16 at 18:20
  • systemctl --failed lists 0 failed entries – Filicado Jan 18 '16 at 10:25
  • Two ideas. 1. Failed to get unit file state for ntp.service: No such file or directory - try removing or disabling ntp. 2. Plymouth might be crashing (like this question). Check dmesg and /var/log/syslog for any crashes or errors. – bain Jan 18 '16 at 11:25
  • No luck with that. So syslog doesn't actually show any new entries for a failed systemd boot. I must say I don't find the systemd output very informative. It is logs a lot of of fails and error messages some of which may just be part of normal operations. If 16.04 dumps upstart I guess I'm out of options and may have to switch distro. – Filicado Jan 22 '16 at 09:30
  • systemd errors should be logged to syslog. Maybe something to do with systemd-journald[471]: Failed to forward syslog message: Connection refused. Could be Debian bug #762700 or some configuration problem with syslog or something else. You could try to fix it, but it might be easier to test a fresh install of 16.04 to see if it's already fixed. – bain Jan 22 '16 at 12:01
  • True although as mentioned the 15.04 was a fresh install thanks for your efforts in any case – Filicado Jan 22 '16 at 13:00
  • If syslog isn't working you can check the errors using journalctl. Try journalctl -xb, journalctl -b -p3 or -p4, or journalctl -kp4 to just see the kernel log – bain Jan 22 '16 at 14:15
  • did the journalctl -xb this morning, may have something to do with this:

    1373:Jan 22 09:18:19 lc-m systemd[1]: Dependency failed for /mnt/SeqData1. 1374:-- Subject: Unit mnt-SeqData1.mount has failed 1378:-- Unit mnt-SeqData1.mount has failed. 1381:Jan 22 09:18:19 lc-m systemd[1]: Dependency failed for Local File Systems. 1382:-- Subject: Unit local-fs.target has failed 1386:-- Unit local-fs.target has failed.

    or:

OK this is silly but I found the solution the error had to do with an /etc/fstab entry for an USB drive:

/dev/disk/by-label/SeqData1 /mnt/SeqData1 nosuid,nodev,nobootwait,nofail,noauto,x-gvfs-show 0 0

I had to comment this one out and systemd booted fine. Why this entry for a USB drive was there in the first place I'm not sure. I tried first using nofail and nopootwait but that didn't help. Still confused about all this but the problem is solved.
