I noticed today that I had both an update for Home Assistant Core (I believe to 2021.5.1). After clicking update and waiting for a backup snapshot to be created, the screen just went back to the main Supervisor screen with no indication of an update taking place.
However, when I refreshed the page, I got a “This site can’t be reached”, so I figured the update must have been taking place. After about 3 hours (I went out for a bit), I tried to access HA again, but I still got the same “This site can’t be reached” message.
I tried reaching my Raspberry Pi through Putty/SSH, but I now get a “Network error: connection refused” message. After waiting for another half hour, I decided to unplug the power and reboot the system. Pinging the IP gave me an indication when it was back up, so I refreshed the page again, and I am still not able to reach it.
I figured maybe something went wrong with the update, so I plugged the SD card into my pc to see if I could manually restore the snapshot, but I’m only able to access the hassos-boot partition, with no useful information.
Does anyone have any idea what is wrong and how I can restore my installation?
