Unable to get supervised to install on debian

Hey all,

I have been going around in circles with trying to link my TrueNAS Scale Home Assistant instance to Cloudflare to find out I have not got the right version with add-ons and so needed to spin up a VM to run the Supervised version.

I have debian running on my VM in TrueNAS and have managed to install the OS 1.6.0.
I have verified this with the command in debian and can see it there.
however when I then try the following command i get the error below

dpkg -i homeassistant-supervised.deb

error processing archive homeassistant-supervised.deb (–install):
pre-dependency problem - not installing homeassistant-supervised
Errors were encountered while processing:
homeassistant-supervised.deb

I am running the commands under the SU (root) but this is still giving me this error.
I tried removing the downlaod and trying again but I get the same error time and time again.

Any help would be amazing

Not a huge linix user so be kind!

Here is the best guide. However, since you are doing it in a VM anyway, unless you have some very specific reasons why not, you should just be running HAOS in that VM (and the people that wrote the below guide would tell you the same as well) -
