Install Home Assistant Supervised

Reference: https://docs.home-assistant.io/installation/supervised-installation/

curl \
dbus \
jq \
libglib2.0-bin \

curl -fsSL get.docker.com | sh

Step 3: Install the OS-Agent

Download the latest Debian package from OS Agent GitHub release page at:

https://github.com/home-assistant/os-agent/releases/latest

wget https://github.com/home-assistant/os-agent/releases/download/1.6.0/os-agent_1.6.0_linux_x86_64.deb 
sudo dpkg -i os-agent_1.6.0_linux_x86_64.deb

Step 4: Install the Home Assistant Supervised Debian Package

wget -O homeassistant-supervised.deb https://github.com/home-assistant/supervised-installer/releases/latest/download/homeassistant-supervised.deb
sudo apt install ./homeassistant-supervised.deb

Step 5: Fix "Unsupported system - Network Manager issues"

Reference: https://community.home-assistant.io/t/debian-12-ha-supervisor-installation/640446/19

I think I¡¯ve found a solution. The problem is indeed with the cloud images of Debian. They come with netplan and systemd-networkd. This prevents Network Manager from taking over the interface. So the solution is:

sudo apt remove netplan.io
sudo systemctl disable systemd-networkd
sudo reboot
