Comment 4 for bug 1990542

No, aoetools is not at fault here. The initrd does not take your netplan configuration into account. You could specify the ip= kernel parameter to let the initrd setup your network as you want it, but initramfs-tools does not have any support for brigdes as far as I know.

If you do not need/use aoetools, then you can just remove that package or specify "ip=off" on the kernel command line to disable configuring the network in the initrd.
