The booting process ends in a terminal. No lightdm, no graphic screen. The file system is read only. It is a systemd problem, because I can use upstart with no problem.

[Gilbert Dion]

1) Release: Ubuntu 15.04
2) version of the package: systemd-sysv 219-7ubuntu4
3) Expecting: login screen (lightdm)
4) happened: terminal screen non graphic and a read only system.

You reported this under upstart, so there are no logs yet to diagnose the problem. Please boot with systemd, and describe what you see: do you get an emergency mode root shell? If not, do you get a "login:" prompt on the text console? If neither, please do a screenshot (with a camera).

Then boot back with upstart, and attach /var/log/syslog. Thanks!

[Gilbert Dion (diong)]

First, I reinstalled systemd-sysv and ubuntu-standard which were
uninstalled with the installation of upstart.

Booting doesnt get me any emergency mode root shell nor a login prompt: all
I have is a totally black screen, as if it was turned off.
I used to get a login prompt in systemd when I tried an earlier kernel
(3.19.0-15) than the current one (3.19.0-16). But this does not occur
anymore.
Her is my syslog. I started with systemd at 13:59. Only two lines appear
ending with error 15.
Then I started with upstart at 14:04.
I later tried again systemd at 14:06 and 14:07
Then back with upstart at 14:14

Thanks,

Gilbert Dion

OK, thanks, so /var/log/syslog is useless here. Can you please boot with the systemd debug shell as described in /usr/share/doc/systemd/README.Debian and also drop "quiet" and "splash" from the "linux" line in grub. Do you get some output then? Can you switch to the debug shell at Ctrl+Alt+F9? If so, please do a 'journalctl -b > /root/journal.txt", then reboot with upstart and attach /root/journal.txt here.

[Gilbert Dion (diong)]

Hi,

Sorry, I didn't have time before today to try what you suggest.

So I added hte init=/bin/sysetmd to the grub command line and I installed
the /var/log/journal. I could open a terminal on VT 9.

When I tried to journalctl -b >root/journal.txt I had the message "Read
only file system". So I mounted a OSB storage device to store the journal.
Please find it attached.

Thanks for the journal! Here we are:

Jun 07 14:03:23 gilbert-iMac systemd[1]: Starting Remount Root and Kernel File Systems...
Jun 07 14:03:26 gilbert-iMac systemd-remount-fs[522]: mount: can't find UUID=8cf7c301-3916-43a5-bef4-57bb02a1cdc3
Jun 07 14:03:26 gilbert-iMac systemd-remount-fs[522]: /bin/mount for / exited with exit status 1.
Jun 07 14:03:26 gilbert-iMac systemd[1]: systemd-remount-fs.service: main process exited, code=exited, status=1/FAILURE

So it seems your /etc/fstab contains an invalid entry for the root partition. Can you please check "sudo blkid" for what the correct UUID is for your root partition, and update it in /etc/fstab? If you don't know how to do that, please just give me the output of

  cat /etc/fstab
  sudo blkid

(under upstart is fine), and I'll tell you how to adjust it.

[Gilbert Dion (diong)]

That was it. I changed the invalid UUID for the correct one and everything
is fine now. As I can see, I was not the only one to have this problem.
Thank you Martin for your excellent support!
