I received my Omega2 Pro today and started setting it up this evening.
During the initial setup, the web interface 'hung' during the firmware upgrade. I reloaded the browser and was able to login to the console.
Running oupgrade -c, I found I needed to upgrade still.
When I ran oupgrade, I got the error message:
/usr/bin/oupgrade: local: line 378: not in a function
I went looking in the Onion GitHub repos and found this patch at https://github.com/OnionIoT/oupgrade/commit/941a638283e2acfefe5fdab33886cdd672d949a8
I made the one line change to the script and was able to run oupgrade.
You'll also need to run the onion os update command to get the new apps once you've upgraded the firmware.
I guess some of the boards didn't get the latest patches before they were shipped?
Cheers,
