How can I boot into recovery mode if it hangs booting into single user mode?



I am trying to boot into "recovery mode" or any single user mode, but upstart is trying to start modem-manager no matter what. It says "modem-manager could not connect to system bus" and sits there retrying, forever.



Can I boot into single user mode and tell upstart to NOT try starting the modem?



Can I boot single user and tell upstart to start a shell after drives are mounted? Thanks for any help in advance...



UPDATE: I was able to use the grub init=/bin/bash trick to get a command prompt on booting. From there I was able to apt-get purge modemmanager. But I still get an error about can't connect to system bus and a hang. Is there a way to put upstart into extra verbose mode so I can see what is causing the hang?

After a lot of Googling the different terms, I found a post that may solve your problem also.



For me that was a bug for Ubuntu 11.10. Take a look at this post for solution.
And to repeat the solution here:




  1. Hit Ctrl+Alt+F1 at the blank screen to get you to a non-X terminal (tty1)

  2. Login in with your username and password

  3. Change to root with: sudo -i and enter your password

  4. mkdir -p /run /run/lock

  5. rm -rf /var/run /var/lock

  6. ln -s /run /var

  7. ln -s /run/lock /var

  8. Reboot
