Okay, I've now been able to reproduce the problem in a Focal LXD container.

Steps to reproduce:
1) Have netplan 0.101 installed
2) Upgrade ONLY libnetplan0 to 0.102
3) remove
4) Execute '/usr/lib/systemd/system-generators/netplan /run/systemd/generator /run/systemd/generator.early /run/systemd/generator.late'

root@ff:~# dpkg -l | grep netplan
ii libnetplan0:amd64 0.102-0ubuntu1~20.04.1 amd64 YAML network configuration abstraction runtime library
ii netplan.io 0.101-0ubuntu3~20.04.2 amd64 YAML network configuration abstraction for various backends
root@ff:~# rm /run/systemd/generator/netplan.stamp
