In Ubuntu 18.04 the default network configuration is done with netplan. I have a setup which creates a bridge interface at startup, see below.
It all works great, except that during startup it runs into a timeout of about 2 minutes. After the timeout it finishes the startup, and the system runs without problems.
For 2 minutes it prints this message on the console (also present in /var/log/boot.log)
A start job is running for Wait for Network to be Configured
I have several systems with Ubuntu 18.04 and netplan, but only the ones with a this bridge interface have this problem.
Does anyone else see this too?
This is my netplan config
network: version: 2 renderer: networkd bridges: testbr0: addresses: - 10.82.0.1/24
BTW. I'm using this bridge for LXD. At startup there are no LXD containers yet that use this bridge.
