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Update the local keyring with the archive keyring and remove from the local keyring the archive keys which are no longer valid.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
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 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.
