NAME

apt-key - APT key management utility

CONTENTS

SYNOPSIS

apt-key [--keyring filename] {add filename | del keyid | export keyid | exportall | list | finger | adv | update | net-update | {-v | --version} | {-h | --help}}

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 the filename given with the parameter filename or if the filename is - from standard input.

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Update the local keyring with the archive keyring and remove from the local keyring the archive keys which are no longer valid.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 debian-archive-keyring package in Debian.

net-update

Perform an update working similarly to the update command above, but get the archive keyring from a 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, relying on update instead, but Ubuntus 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 particular 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.

FILES

/etc/apt/trusted.gpg

Keyring of local trusted keys, new keys will be added here. Configuration Item: Dir::Etc::Trusted.
