I have updates installed with approvals. I approved the update a few minutes ago and the router rebooted without asking after the update. Again, for like the 4th update in a row. I think this starts to be serious and you should have a look at it soon or people are gonna be really pissed by the unwanted reboots in the middle of the day.
I also got this error notification after the unwanted reboot:
Updater failed:
[string "transaction"]:327: [string "transaction"]:238: attempt to index local 'upgraded_packages' (a nil value)
