Installing Home Assistant Supervised using Debian 12

Every time I boot the machine resolv.conf in overwritten.

man NetworkManager.conf

1. Using the CLI edit /etc/NetworkManager/NetworkManager.conf

2. Search for the [main] section in this file. It should look something like this:

[main]
dns=default
plugins=keyfile
autoconnect-retries-default=0
rc-manager=file

3. Now change dns=default to dns=none just after the [main] tag like this:

[main]
dns=none
plugins=keyfile
autoconnect-retries-default=0
rc-manager=file

4. Save the file and restart NetworkManager.service:

sudo systemctl restart NetworkManager.service

5. Edit resolv.conf and add the DNS-server of your choice.

Next time you reboot your /etc/resolv.conf file will not get updated when using nm (network-manager).

Hope this helps.
