U2->U2.1 Upgrade error message

[o0o]

Hi,

I tried to install the uppgrades from today (U2.1). I clicked install and reboot. Unfortunately, at the end of the install I got this error message: see screenshot.
What's the problem and how to solve it?

Thanks for helpful hints!

I do not know what is wrong, but few people here will NEED this upgrade. So avoid it by not upgrading
From the release notes:
[NAS-109434] - Resolve issues with joining Active Directory Domains
[NAS-109454] - Suppress extraneous corefile alerts
[NAS-109490] - Use the correct verbiage when Applying Pending Updates for HA

Thanks. I restarted the system. After restart it shows: TrueNAS-12.0-U2.1 and no updates available...
