The problem (at least in my case) is that "shutdown" needs root privileges and during the upgrade to natty (and btw everytime I upgrade to a new Ubuntu version) the privileges of shutdown are restored to the default ones. Hence after every upgrade i have to run the following command on a terminal
sudo chmod u+s /sbin/shutdown I hope this help you Alex. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757367 Title: Gshutdown doesn't shutdown -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
