Hi, I run HA on a Raspberry Pi 4 with DietPi v7.8.2 and just updated from 2021.8.8 to 2021.11.3 with the dietpi update script without any issues visible during the update process.
After the successful update, I tried to restart HA server, but it warned me:
Logger: homeassistant.components.websocket_api.http.connection
Source: helpers/check_config.py:27

So now the system is running the old version and I am afraid it might not start up again after updating DietPi and restarting the HA service due to the error, and also I would be stuck with version 2021.8.8 
If I check “/home/homeassistant/.pyenv/versions/3.8.10/lib/python3.8/site-packages/homeassistant/requirements.py” I find
@callback
def async_clear_install_history(hass: HomeAssistant) -> None:
"""Forget the install history."""
if install_failure_history := hass.data.get(DATA_INSTALL_FAILURE_HISTORY):
install_failure_history.clear()
so why can’t the function not be imported and I do anything to fix this or work around it? I tried to google the error message, but I did not find anything that helps me.
I did the update because I tried to install HACS before, but when I wanted to activate the integration it told me my HA version was outdated. So then I did the update and I guess the error might also be caused by the HACS installation. What I did to install HACS was to run
root@DietPi:/mnt/dietpi_userdata/homeassistant# wget -O - https://get.hacs.xyz | bash -
So now I tried moving the hacs files somewhere else, hoping this might avoid the installation of HACS and not cause the error, but I got the same error when trying to restart HA. It was probably a stupid thought anyway, because the installation was done when I ran the script.
Sorry if this a dumb question, sorry for my english and thanks for any helpful advice pointing me in the right direction… I would also appreciate notes from advanced users that no one will bother to help me because the problem is so obvious (like when I missed some instruction) or so specific and unique that it is not worth looking into and rather restore the backup. I do have an up to date backup I can restore, but I would rather figure out what is wrong and how to fix it, also because I would guess that I run into the same issue after trying to update from my backup of 2021.8.8.
Here are some more info about my system (Raspberry Pi 4 with DietPi v7.8.2):
