[547931193200] Error updating Home Assistant Operating System: āOSManager.updateā blocked from execution, system is not running - CoreState.STARTUP
Several hardware reboots didnāt fix it, unfortunately.
Aaaaaand after about a dozen attempts, suddenly today it simply works.
Previous attempts would have a progress indicator for six or eight minutes, which would disappear, then the system would reboot, and then come up still on HAOS 8.5.
I wish I knew what I could do differently next time, other than āwait until Day Two,ā I guess.
