apt-keyコマンドは非推奨らしいので、gpgコマンドでdearmorする練習とメモ

Ubuntu 22.04 で apt update すると以下のように警告を受けるようになった

# apt update

...

W: https://download.newrelic.com/infrastructure_agent/linux/apt/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.
