I've been trying to upgrade my TL-SG2210P from v5.0.2 to v5.0.3 for the past few hours but it won't ever complete. At first I was on Omada SDN Controller v5.5.6, but have switched to 5.6.3 to see if a newer controller version would help (it did not). I am currently running the controller in a Docker container, but have successfully updated other device firmware in the past, so I don't think there's any configuration issues there.

Watching the Omada logs, it checks every second or so for the upgrade to complete and eventually fails after roughly 10 minutes:

Any ideas? I thought of removing the switch from the SDN and trying to upgrade via the switch's interface directly, but i'd like to avoid having to reconfigure the switch afterward, and am still not 100% sure it'd actually work. I wonder if anyone else has come across errors with this particular firmware upgrade.
