Plex script doesn't set apt signing key

[lightmaster]

A clear and concise description of the issue.

The Plex LXC script creates the keyring /usr/share/keyrings/plexmediaserver.gpg, but it does not set the apt source to use this keyring, resulting in this error message when updating packages in the LXC:

W: https://downloads.plex.tv/repo/deb/dists/public/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

If relevant, including screenshots or a code block can be helpful in clarifying the issue.

No response

Please provide detailed steps to reproduce the issue.

1. Create Plex LXC using script
2. Access via console and try to update apt with apt update

Oh, you're using 22.04, try mv /etc/apt/trusted.gpg /etc/apt/trusted.gpg.d/
