Dear Debian community,

I've exercised several directions to solve the issue, however I've failed. 
Would be great if somebody can share his idea. After upgrading from Debian 
buster to bullseye I still have the same issue:

# systemctl status networking.service
— networking.service - Raise network interfaces

I recently went through something similar where networking.service got obscure errors I couldn't diagnose.

 * systemd.networkd.service
 * networking.service
 * NetworkManager.service

I went against my better judgement and changed to using systemd-networkd.service Rather surprisingly I got a working network with no errors. You could try that approach and see if you have any luck. When you switch, you need to backup /etc/network/interfaces and copy /etc/network/interfaces.default over /etc/network/interfaces. I remain perplexed however why there are at least three different mostly incompatible network management systems :
