Comment 19 for bug 1876884

Hi Yannik,

I think you have two options:
1) Workaround by adding /etc/netplan/xxx.yaml (or any other name which lexically sorts after "enp1s0.yaml"):
network:
  version: 2
  renderer: NetworkManager
  ethernets:
    enp1s0:
      dhcp4: true

2) Cleanup dropbear-initramfs interfaces (as described at "Ask Ubuntu"):
/etc/initramfs-tools/scripts/init-bottom/deconfigure-interfaces:
rm -f /run/netplan/enp1s0.yaml && ip -f inet address flush dev enp1s0

You probably need to run 'update-initramfs -u' afterwards again...

IMO option (2) is actually a proper solution, this is why I am assigning this bug to 'dropbear', as I think it should automatically cleanup the interfaces/configs it created, once they are not needed anymore.
