Arch Linux

Description:

Can't connect to ethernet via networkmanager. The QT UI says it's trying to connect, but then nothing happens. I updated to this version (see below) already a week ago, and it was working until today. dhcpcd DOES WORK!


Additional info:
* package version(s)

networkmanager 1.16.0-1

* config and/or log files etc.

>>journalctl -b -u NetworkManager --no-pager
