Public bug reported: Server info (20.04) After i updated my docker server yesterday i had to reboot because of a kernel update (new version 5.4.0-58-generic x86_64). My main network interface that i use all of a sudden failed to apply its configuration and was not able to connect. I believe this issue is linked to this bug (Bug #1860926) but not exactly the same issue. When setting up my server on first install i used the startup walk-through to auto configure my eno1&eno2 network bond. I unfortunately didn't save the previous netplan yaml to post here,but it had said it was written by subiquity. Every time i tried to apply the netplan it replied that eno2 was not defined. I had to change the yaml to this configuration to get my link back up.
