Upgrading from 24.7.12.4 to 25.1 fails on APU4D4

[angryviking]

Hello guys!

I have the exact same problem as the gentleman in https://forum.opnsense.org/index.php?topic=45505 when upgrading my firewall.

During boot after upgrade it gives the following message and does not complete.

I have been able to rollback using a ZFS snapshot I randomly created. Would be really nice feature if all upgrades created a snapshot automatically by the way :)

Have tried this upgrade 3 times now and still get the same result. All health checks looks good and everything is working perfectly.

Any idea how to upgrade without reinstalling 25.1 and reimporting the config?

I've upgraded APU4D4 without any issue.

Can you post the healthcheck results before attempting the upgrade ?
