Public bug reported: I upgraded my 16.04 to 18.04 before the official release. After the upgrade I noticed that I don't have internet access. The wired network and the wifi settings looked good, but the internet didn't work. After the login the system always switched itself into airplane mode. I tethered the network via USB and Bluetooth by my mobile but they also didn't work.
