apt-key [--keyring filename] [command] [arguments...]
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.
Add a new key to the list of trusted keys. The key is read from
filename, or standard input if filename is -.
Remove a key from the list of trusted keys.
Output the key keyid to standard output.
Output all trusted keys to standard output.
List trusted keys.
List fingerprints of trusted keys.
Pass advanced options to gpg. With adv --recv-key you can download
the public key.
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the local keyring the archive keys which are no longer valid.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.
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.
Note that options need to be defined before the commands described in
the previous section.
With this option it is possible to specify a specific keyring file
the command should operate on. The default is that a command is
Local trust database of archive keys.
Keyring of Ubuntu archive trusted keys.
