Comment 7 for bug 1860926

The following has me wondering if this has partly to do with the presence of containers, VMs and similar items.

I upgraded my router to 20.04 a few days before release. (Plain Ubuntu command-line OS on a PC Engines APU1 board) That machine has a bridge network comprising two ethernets and one wifi. I've had no problems with it - it comes up nicely on boot. Whereas I have to use the crontab workaround on my main PC which has a bridge for VMs.

I'm not clever enough to imagine why this might be the case, but I thought it might be worth noting.
