Hi,
An attempt to update Host OS version (from balenaOS 5.3.22 to balenaOS 6.5.50+rev2) on a RPI5 has failed (likely because of unstable internet connection) and the device seem to get stuck in the “Configuring (OS update failed)” status.
The device itself is still up & running and I get ssh.
“Reboot” fails with “Operation failed with: Supervisor locked” error.
How to recover from this / retry Host OS update?
Hi, the balenaCloud dashboard will allow you to retry the update. If you just want to clear the message, restarting the supervisor will do.
the balenaCloud dashboard will allow you to retry the update
This does not seem to be working - when I try to repeat the update, it just says “Operation completed successfully” but then nothing happens.
If you just want to clear the message, restarting the supervisor will do.
Neither of those help - am I doing it wrong?
systemctl restart balena-supervisor
systemctl restart balena
And I still get “Operation failed with: Supervisor locked” error when I try to reboot the device from the UI or “Waiting for Host OS update to finish” if I try to do it via supervisor API.
Can you post the Host Update (HUP) log for the most recent update attempt? It’s in /mnt/data/balenahup/.
Here is the log from the most recent attempt (there are multiple attempts - all logs look the same)
$ cat /mnt/data/balenahup/upgrade-2.x.sh.20250924_120514.log

@alanb128 are these logs useful? Anything else I can try to recover from this state? (it’s at remote location, so physical access it tricky)
