Signature expired - preventing access to repo

[coderbec]

Description
Trying to install on rpi and hitting a snag when trying to set up access to Mariner repo.

Firslty getting a warning on sudo apt-key add that apt-key is deprecated so I switched this this command:
curl -sL gpg.l9o.dev | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/mariner3d.gpg

However, the signature itself is I think expired:
GPG error: https://ppa.l9o.dev/raspbian ./ InRelease: The following signatures were invalid: EXPKEYSIG BF6F8043AC280E02 Luiz Ribeiro <luizribeiro@gmail.com>

For people who want to continue anyway (highly discouraged, yadayadayada...):

edit /etc/apt/sources.list.d/l9o.list by adding [trusted=yes]

deb [trusted=yes] https://ppa.l9o.dev/raspbian ./

any other way to get this working because stil expired

You have to add the key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys BF6F8043AC280E02

I have dug thru alot of the documentation, I found this thread, after adding the key, I still cant seem to get access to the repository either. Looks like the key has expired.

For me it is working:

`pi@elegoo: $ curl -sL gpg.l9o.dev | sudo apt-key add -

Looks like https://gpg.l9o.dev/ is no longer up. However, the key can still be added directly from the keyserver. I got @MarkGyver-source's process working and have copied it here for a bit better readability

echo "deb https://ppa.l9o.dev/raspbian ./" | sudo tee /etc/apt/sources.list.d/l9o.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys BF6F8043AC280E02
sudo apt update && sudo apt install -y mariner3d
