Job for husarnet.service failed because a fatal signal was delivered causing the control process to dump core.
See "systemctl status husarnet.service" and "journalctl -xeu husarnet.service" for details.

We’ve had this failure on two different systems now – on the other one (1 week ago), it just started working with no explanation. We’ve also had this install succeed on numerous RPi Ubuntu 22.04 systems very similar to the one that is failing now.

I’ve tried removing/reinstalling multiple times and it fails every time. One other thing of interest is the /var/lib/husarnet directory is created but is empty.

Here is part of the journalctl output:
