APT-KEY

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Update the local keyring with the archive keyring and remove from the local keyring the archive keys which are no longer valid.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 executed on the trusted.gpg file as well as on all parts in the trusted.gpg.d directory, though trusted.gpg is the primary keyring which means that e.g. new keys are added to this one.
