I’m running Supervised HA on a System where is installed Openmediavault 6.
I had the journal issue as well as NetwokManager issue and also the CGroup version issue.
I did exactly:
apt-get install systemd-journal-remote -y
wget https://github.com/home-assistant/supervised-installer/releases/latest/download/homeassistant-supervised.deb
dpkg -i homeassistant-supervised.deb
I rebooted and everithing seems to be ok.
The logs are working and no issues reported.
thank you!
