Thank for your bug report.

Based on the core dump you provided, the problem seems to be related to libnetplan.

Can you collect the NetworkManager's systemd journal and attach to the ticket, please?

journalctl -u NetworkManager > network-manager.log

Thanks!

So,

the problem appears to be the value of "cloned-mac-address". Netplan only accepts a MAC address, but Network Manager also supports some special settings ("preserve", "permanent", "random" and "stable").

I prepared a fix for that https://github.com/canonical/netplan/pull/376
