APT-KEY(8) APT APT-KEY(8)NAME
apt-key - APT key management utility
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the local keyring the archive keys which are no longer valid.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 ubuntu-keyring package in Ubuntu.
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 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 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.
