I upgraded to Ubuntu 14.04 today and I have two problems
1) When ever i do 'sudo' followed by a command the system just stalls, nothing from 'sudo ls' to 'sudo apt-get install ... ' etc works. The system just waits and waits.
2) My networking is never starting. I cannot connect to internet at all. no ethernet and no wireless. The tray icon is missing. /var/lib/NetworkManager/NetworkManager.state tells my networking is enabled. I cannot edit any system files because I cannot 'sudo'!
however, when I enter recovery mode, everything seems to be fine. 'sudo' works and networking also works!!!. Can somebody help me please.
