OS upgrade

Configuration
1

Hi, this might be a stupid question, but I couldn’t seem to find any info on this. Which I found slightly surprising, so maybe I’m just googling the wrong things?

Anyways, is it possible to upgrade the OS (in this case from raspbian jessie to stretch) while keeping homeassistant (in this case installed in virtualenv) and the things it needs (mosquitto, mariadb, duckdns w. letsencrypt, etc.) working?

Having upgraded the last 7 versions of Ubuntu without any problems, I’d say you shouldn’t have any problems upgrading from Jessie to Stretch. Have a look at this page for a how to:

Thanks, that’s what I would have though. But after doing that, HASS wouldn’t start. And sudo systemctl status [email protected] showed:

And when I tried to upgrade HASS, I also had issues:

sudo su -s /bin/bash homeassistant
homeassistant@hassbian:/home/pi$ source /srv/homeassistant/bin/activate
(homeassistant) homeassistant@hassbian:/home/pi$ pip3 install --upgrade homeassistant
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ImportError: No module named 'encodings'
Aborted

So for now, I used the image I (luckily) backed up before upgrading the OS.

After moving, and getting some time to play with home assistant again, I found a solution. If anyone finds this thread looking for answers, try the link (I had to start at step 2 though, not step 3).
