Installing on Debian 11 and the GrayLog documentation appears to be wrong

I’m very new to Graylog and I have been doing a lot of sandbox testing to find a log aggregation solution that will do what our little group needs. I was following the documentation for the installation of GrayLog from the main website. The link in question is here. It appears that the installation process for Mongo calls out this line:

wget -qO - | sudo apt-key add -

But when I run it on my fresh Debian 11 box I get the following errors:

logs:~$ wget -qO - | sudo apt-key add -
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
gpg: no valid OpenPGP data found.

Is there current documentation elsewhere? I’m not sure what to substitute here to make this work.

Hey @Gorf and welcome

If that documentation doesnt work perhaps go to MongoDb. Specially this section of the documentation here

See if that works for ya.

@Gorf Did you get this working?
We did see some updates for mongodb related to SSL libraries updates. We could see they made changes to better support ubuntu in V6.0.4. Did you try using specific version 6.0.4?

Why on earth use mongodb when there’s mariadb/mysql ?
My install on a default debian 12 failed as well.
