i installed debian 12 supervised today the only thing i needed to do before installing disable modemmanager install systemd-resolved i always when installing HA copy past commands from here so it also installs jq wget curl udisks2 libglib2.0-bin network-manager dbus systemd-journal-remote Installing Home Assistant Supervised on Debian 11 - Community Guides - Home Assistant Community (home-assistant.io) all works fine auto discovery and addons no issues for now yes unsupported OS so unsupported system but i install things outside HA anyway so my setup always shows unsupported but as long as it shows healthy im ok with that. i thought i test 12 im going to move my 5/6 year old debian install to new machine with proxmox and debian in VM but im still bit scared it all works so well i used clonezilla to copy the phisical drive to VM drive but its going to be a mess because it uses nvidia GPU for plex jellyfin ffmpeg compreface frigate etc and the new one has only Iris Xe igpu but all for less power usage its a old dell server the new one gen12 i7 1270p. but to use the iris xe as vgpu in debian i at least need kernel version 6.1 so debian 12 would be perfect because it comes with 6.1.
