Just wondering... Why the third-party Java 8?

I skipped that part of your script and just did this:

# apt install openjdk-11-jre-headless

And everything works as advertised. Thanks!

Thanks @counterpoint ! Shame on Ubiquiti for the official instruction and still using end-of-life MongoDB 3.6.

And the oldest version offered for Debian 11 is Mongo v4.2 🙄

Updated to debian 12 bookworm and unifi 8.0.
Tested on 2023-11-17, with debian 12.2 and unifi 8.0.7

Works fine on a freshly upgraded Debian 12 (amd64). Thank you!

I'll note that if you're going with a very minimal Debian 12 install, you'll need to install curl and gpg
sudo apt install gpg curl -y

Otherwise worked perfectly - excellent guide.
