Hassio upgrade from 0.50.2 to 0.51.1 gives Unknown Error

I have tried a few times with command line and UI with the same results. Not much in the way of logs either.

This is all I get:

I don’t seem to be alone:

this update broke my entire system, had to do a full reset with a sdcard re flash. luckily I had a back up, but SSL is totally broken. Please add a Revert option for the updates. or at least let us install other versions on Hass.io

Same situation and I’m getting the exact same error. Haven’t found a resolution yet.

It give a error like this, if the SD card is to small to fetch the update

I’ve chased that down but I don’t see how space is an issue…mapping the SMB \share directory (e.g. \hassio\share) from windows shows space free @ 9.69GB. SSH’ing in and running df -h shows the same…

core-ssh:/# df -h
