ValueError: bad marshal data (unknown type code)

Installation

EDIT i reformatted SD card as apt-get threw errors so I can’t diagnose this anymore.

I just attempted an upgrade from 0.62.1 to to 0.82.1 on Rassbian. Upgrade appeared to work BUT hass will no longer start, getting:

pi@hassbian:~ $ sudo systemctl status [email protected]

I’m not getting any hits on this. This implies some sort of byte code load (*.pyc or frozen) problem. I have no idea how to go about debugging this. Any hints would be appreciated. I had previously upgraded to 0.76.2 successfully (on another SD card) and was finally ready to take the plunge into the new auth system.

More traceback information, from:

sudo -u homeassistant -H -s
source /srv/homeassistant/bin/activate

Output:

So test case to demo problem is:

at-get os upgrade resulted in error so I ended up wiping the card and going to 0.76.2.

I’ll try again tomorrow :slight_smile:
