Updating apt results in the following warning:
W: http://ppa.launchpad.net/ondrej/php/ubuntu/dists/jammy/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
W: https://mirror.rackspace.com/mariadb/repo/10.11/ubuntu/dists/jammy/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

Latest Trellis was provisioned after those apt warnings, but this did not resolve the issue.
