apt-key


SYNOPSIS
       apt-key [--keyring filename] [command] [arguments...]

DESCRIPTION
       apt-key is used to manage the list of keys used by apt to authenticate
       packages. Packages which have been authenticated using these keys will
       be considered trusted.

COMMANDS
       add filename
           Add a new key to the list of trusted keys. The key is read from
           filename, or standard input if filename is -.

       del keyid
           Remove a key from the list of trusted keys.

       export keyid
           Output the key keyid to standard output.

       exportall
           Output all trusted keys to standard output.

       list
           List trusted keys.

       finger
           List fingerprints of trusted keys.

       adv
           Pass advanced options to gpg. With adv --recv-key you can download
           the public key.

       update
           Update the local keyring with the archive keyring and remove from
           the local keyring the archive keys which are no longer valid. The
           archive keyring is shipped in the archive-keyring package of your
           distribution, e.g. the ubuntu-archive-keyring package in Ubuntu.

       net-update
           Work similar to the update command above, but get the archive
           keyring from an URI instead and validate it against a master key.
           This requires an installed wget(1) and an APT build configured to
           have a server to fetch from and a master keyring to validate. APT
           in Debian does not support this command and relies on update
           instead, but Ubuntu's APT does.

OPTIONS
       Note that options need to be defined before the commands described in
       the previous section.

       --keyring filename
           With this option it is possible to specify a specific keyring file
           the command should operate on. The default is that a command is
           Item Dir::Etc::TrustedParts.

       /etc/apt/trustdb.gpg
           Local trust database of archive keys.

       /usr/share/keyrings/ubuntu-archive-keyring.gpg
           Keyring of Ubuntu archive trusted keys.

       /usr/share/keyrings/ubuntu-archive-removed-keys.gpg
           Keyring of Ubuntu archive removed trusted keys.
