I was out of the country for a significant time and away from home. Found my old HA device on 2021.3.3. I'm struggling updating it because I'm getting an error that the system isn't healthy- docker. Any pointers? I'm pretty much in a whole new home and need to restart from scratch, so I'm not worried about saving old configurations

I've got the odroid n2+, which appears to not use easily removable storage, so I'm looking around to figure out where to go from there'

Thanks!

#

Can I get away connecting it to my pc with a micro usb on the rear port, or do I need a usb male/male cable?
