: It is used to elevate the user's privileges to perform administrative tasks. The command is executed with root/administrator privileges. -
pacman-key
: It is a command-line utility in Arch Linux used to manage the package signing keys. -
--populate
: It is an option that instructspacman-key
to populate the keyring. This means it will add the necessary keys to the keyring to verify the package signatures. -
${archlinux}
: This is a placeholder used to represent the architecture of the system. In the command, it should be replaced with the actual architecture likex86_64
