Have you just upgraded to Ubuntu 11.10 and now getting the Ã¢â‚¬Å“Waiting for network configurationÃ¢â‚¬Â message followed by Ã¢â‚¬Å“Waiting up to 60 seconds more for networkÃ¢â‚¬Â? This then might be accompanied by a black blank screen or screen with text “Booting Ubuntu without full network configurations”?
[update] IÃ¢â‚¬â„¢ve updated this post to reflect the copy step mentioned in the bug post below is surplus as /run is mounted tmpfs Ã¢â‚¬â€œ the refined steps are below. The fix is removing the old /var/run and /var/lock then pointing those old locations to /run and /run/lock respectively. IÃ¢â‚¬â„¢m suspecting this bug only comes about after an upgrade from your existing session (e.g. apt-get dist-upgrade) where it must have trouble removing these directories because existing services have files needed in there.
The bug is here (https://bugs.launchpad.net/ubuntu/+source/sysvinit/+bug/858122) and the fix is based on this: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/811441/comments/24 :
- Hit Ctrl+Alt+F1 at the blank screen to get you to a non-X terminal (tty1)
- Login in with your username and password
- Change to root with: sudo -i and enter your password
- mkdir -p /run /run/lock
- rm -rf /var/run /var/lock
- ln -s /run /var
- ln -s /run/lock /var
You should have 11.10 back again.
