After installing Ubuntu 18.04 wifi authentication failure happens.

Asked by jake on 2018-07-14

After installing Ubuntu 18.04 wifi worked fine for about two weeks, then authentication failed. Wifi settings has not been changed and other devices work fine.

After removing the file in /etc/NetworkManager/system-connections/ the problem disappeared.
