说明
pacman-key is a wrapper around GnuPG for managing the keyring used by pacman to verify package signatures. It handles key initialization, importing, signing, and trust management. On a fresh Arch Linux installation, run --init to create the keyring, then --populate to add the official Arch Linux packager keys. For third-party repositories (like AUR helpers or custom repos), manually add and sign their keys. Key signing (--lsign-key) marks a key as trusted, allowing pacman to install packages signed by that key without warnings.
