Stopping early crypto disks [Fail]

Stopping early crypto disks [ok]

umount /run/lock: not mounted

umount /run/shm: not mounted

mount: / is busy

Will now halt


Solution:1

Are you taken to the lock screen (login)? Or is it hanging at the ubuntu magenta screen?
Try running:

sudo shutdown -c  sudo shutdown -h now  

-c cancels scheduled halts and -h halts the session. These errors happen when an application vetoes the halt; check with gnome-system-monitor for any running scripts or processes that is causing this. Close them and try a normal shutdown from the panel.
