You won’t believe it (and I still don’t) but I was finally able to upgrade my Intel NUC10 (Model NUC10i7FNH) from Umbrel 1.5 to 1.7.3. I stopped all apps, shut down, installed the new BIOS, rebooted, clicked upgrade, and it successfully rebooted with the new version installed. ALL Umbrel Apps work after the upgrade.
What prompted me to try again? ASUS released a new BIOS for my NUC10 on 06/11/2026.
