Bug Description
Ubuntu 20.04
network-manager:
Installed: 1.20.4-2ubuntu2
Candidate: 1.20.4-2ubuntu2
Version table:
*** 1.20.4-2ubuntu2 500
500 http://
100 /var/lib/
After going to kernel 5.4, from 5.3, I noticed the network systray roundel going 'round and 'round. On closer examination I could see that the Wi-fi had connected but the Ethernet connection was "obtaining IP address" --> fail --> back to "obtaining IP address" and continually going around and around.
Doing a "service NetworkManager stop" and quickly following up with "service NetworkManager start" fixes the situation. However, if you leave any kind of a gap between the stop and start the issue described above starts up again.
I also left a freshly booted system for quite a while and went back to it but the issue was still there, until the workaround described above was performed.
Booting up in to kernel 5.3 the issue is not seen and all network interfaces connect as expected.
