I’ve made a code analysis on the homeassistant-supervised.deb package and found an OS check bypass mechanism:
Once again, use this only if you REALLY know what you are doing and don’t whine to anyone if it doesn’t work or breaks something.
sudo BYPASS_OS_CHECK=true dpkg -i homeassistant-supervised.deb
Hope it helps anyone as it helped me.
