Hello Maybe this will help someone I solved the problem myself in this way: I added at the end of /etc/acpi/powerbtn.sh the command /etc/init.d/networking stop
so it looks like: # If all else failed, just initiate a plain shutdown. /etc/init.d/networking stop "Network shutdown" /sbin/shutdown-h now "Power button pressed" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010045 Title: 12.04 hangs on shutdown deconfiguring network interfaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1010045/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
