While upgrading from 13.10 to 14.04 we got a power cut: When we restarted the machine we got a system fail; I'm getting the readout below:

'Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further errors will be ignored. Enter root password or CONTROL-D to continue maintenance.'

Question: How do I get to maintenance shell stage?

Restart the PC and Press and hold the

SHIFT

Key to get the Advanced options and choose Recovery mode

After reaching this screen choose

drop to shell

Drop to root shell prompt

Then Run the command

mount -o remount rw /

This will make the / as read and write

then do your installation steps

  • after selecting 'resume' from the recovery menu I get this: 'you are now going to wait recovery mode and continue the boot sequence. please note that some graphic drivers require a full graphical boot and so will fail when resuming from recovery. if this is the case, simply reboot from the login screen and then perform a standard boot' – angela Aug 14 '14 at 10:20
  • ... then after selecting 'OK' we get: 'FILESYSTEM CHECK OR MOUNT FAILED. A MAINTAINANCE SHELL WILL NOW BE STARTED. CONTROL-D WILL TERMINATE THIS SHELL AND CONT.. BOOT AFTER RETRYING FILESYSTEM. FURTHER ERRORS WILL BE IGNORED. GIVE ROOT PASSWORD FOR MAINTAINANCE OR TYPE CONTROL-D TO CONTINUE' – angela Aug 14 '14 at 10:24
  • pressing SHIFT after restart had no effect so we selected 'UBUNTU, WITH LINUX 3.2.0-67-GENERIC (RECOVERY MODE)' from the menu to get to recovery menu – angela Aug 14 '14 at 10:29
  • give the Root passoword, seems you have already assigned a root password – Babin Lonston Aug 14 '14 at 10:33
  • no idea what the root password is, I tried various passwords at that stage ...maybe the first password was accepted ... will try that again – angela Aug 14 '14 at 10:41
  • OK tried first password again and getting: 'root@baboon-H61M-S2OV:(squiggle hashtag)' and a flashing underscore which means I can input – angela Aug 14 '14 at 10:47
  • ok now run the command mount -o remount rw / – Babin Lonston Aug 14 '14 at 12:13
  • Then try to update restart the network using /etc/init.d/networking restart then upgrade it as before what you done – Babin Lonston Aug 14 '14 at 12:14
