If you install the following packages, you’ll have everything you need to use the “appliance” configurations:
sudo apt install asl3 asl3-update-nodelist asl3-menu allmon3
You will still need to do certain things like configure Allmon3 by hand.
If you want to turn your configuration you described into the full appliance, you can try installing asl3-pi-appliance which will “Take over” your system. I haven’t rigorously tested it against a non-Pi installation but it should mostly work if not completely work - but YMMV. I non-PI “image” is in the works, but it’s not ready yet.
If you don’t want to take the risk of that, but still want all the web experience, you can install:
sudo apt install cockpit cockpit-networkmanager cockpit-packagekit \
cockpit-sosreport cockpit-storaged cockpit-system cockpit-ws \
python3-serial firewalld
And then have the unbranded, uncustomized Cockpit environment too.
