I tried to upgrade to the latest version of HA a few days ago and, even though the upgrade said it was successful, the WebUI did not come back online. I probably should have stopped and started asking for help here at that point. However, I proceeded to troubleshoot on my own. I finally have the WebUI running, but is seems like HA is not completing the bootup process. I cannot get HACS to run, it keeps stating that it is still waiting for HA to start running. My log file is full of errors, one of which is below:
Traceback (most recent call last):

I suspect the error with BytesIO is related to the Ubiquiti integration. I have a lot of automatians tied to Ubiquiti devices and entities. Does anyone have any thoughts on how I might fix this?
I have messed around following various troubleshooting topics that I am wondering if I would be better off reinstalling HA. What files would I need to save to keep all my scripts and automations?
The message is from running ‘tail -f home-assistant.log’ in one SSH session on the RPi and watching while HA is stopped and restarted via ‘systemctl’ on a separate SSH session.
What file(s) are you transferring to your new install? Or are you rebuilding everything from scratch?
Did you also upgrade Python (min version required is 3.8)? What is your Python version? BytesIO is a built-in a Python module so either your Python installation is now broken or something is expecting a different module interface (though I doubt that BytesIO would’ve changed drastically).
Did you upgrade anything else? Maybe a full system update and upgrade via apt would be good.
To back up, there are some other posts about it. In short, create a copy of your whole .homeassistant directory, including your .storage. This will also include the SQLite DB (which I’m assuming you’re using). No need to backup that unless you have a lot of history (which I doubt, since it’s very slow on a PI) that you absolutely want to keep. The storage directory and all YAML files are most important.
Last idea: Delete your DB file (if you don’t mind losing historical data).
Some things started working themselves out it seems. I have verified that I have updated all the standard Raspian packages. After restarting HA and the RPi a couple times yesterday I was able to view the WebUI. I removed a couple integrations that seemed to be having problems. Many of the integrations are working again, including HACS. However, HACS is indicating that it needs to update, but when I tell it to update it will seemingly download the update and then revert back to the page saying that it needs to update. I am not finding anything in the homeassistant.log error message about that issue.
I am also getting a message from HA that it is no longer going to run on Python 3.7 in the near future. I have Python 3.8.5 installed, but I am unsure how to tell HA to us it instead. When I use ‘sudo update-alternatives --config python3’ to set Python 3.8 as the default HA will not start.
I love learning how to fix things, so I am going to continue to try to repair this install. I would appreciate any more suggestions.
Pieter, thank you for pointing out the Phython upgrade and the files that I need to make sure I save.
