Usb, network, shutdown problems after update

view story

http://askubuntu.com – Last night I did an automatic update of ubuntu this morning when I turned on my laptop to connect to the internet was not running, the following appears "NetworkManager is not running ..." and "Networking disable" I tried to go after some solutions, but when I put the pendrive he was not mounting automatically after manually mount I tried to install an old version of network manager, but when I turn off the pc he also shut down, had to type sudo poweroff. Anyone know a solution to this or is having the same problems? (HowTos)
