MattiaBorrelli, If you are feeling adventurous, you can try the instructions given by alex in comment 63, except instead of 'sudo edit /etc/rc6.d/S40umountfs', use the command 'sudo gedit /etc/rc6.d/S40umountfs'.
If you are not feeling adventurous (which is ok), I suspect that one of the Ubuntu updates will take care of this for you. -- Unable to shut down or restart on Karmic https://bugs.launchpad.net/bugs/468589 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
