Problem with network on Supervised Install

My HA install has been working fine for a long time, until last night. A storm knocked out the power and made a mess of the VM I have HA running in. I can boot it, but it’s unable to start the network. I can get in via the console and use dhclient, then the network comes up and everything is fine. Does anyone know much about Debian networking? I’d like to fix this so the network will come up automatically again.

All help is greatly appreciated.

Well… without details abot the usual setup, its hard to say.

Usually you configure the settings for DHCP or static IPs in /etc/network/interfaces

I guess this hint should help to investigate more and fix the issue.
