/usr/share/keyrings for keyrings managed by packages, and /etc/apt/keyrings for keyrings managed by the system operator.
Possible Solution
Download GPG key to /usr/share/keyrings and reference it in newrelic repo file. Or download it to a temporal folder and import it with gpg --no-default-keyring --keyring gnupg-ring:/tmp/newrelic-infra.gpg --import
Additional context
We receive a warning right now, but in a couple of months this will be mandatory when updating. The updated method will also work (at least) in Ubuntu 22.04.
