After updating I have Home Assistant 0.103.6 running. Here https://github.com/home-assistant/core/releases is mentioned that 0.110.0 is the recent version. How I can get this?
I do the update always this way:
sudo -u homeassistant -H -s
source /srv/homeassistant/bin/activate
pip3 install --upgrade homeassistant
thx!
You’ve not been reading the release notes.
Python 3.8 is now supported, so you should build a new venv with that (Python 3.8.3) to give yourself a longer time before you have to do this again. I’ve explained the process here.
Thx that’s the solution, HA still was using python 3.6 since I had forgotten to switch the system default after installing python 3.8:
update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 5
after this and reinstall of homeassistant the actual version is running now 
Thx and best regards
