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.
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.
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the local keyring the archive keys which are no longer valid.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-archive-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.
files
/etc/apt/trusted.gpg
Keyring of local trusted keys, new keys will be added here.
Configuration Item: Dir::Etc::Trusted.
/etc/apt/trusted.gpg.d/
File fragments for the trusted keys, additional keyrings can be
stored here (by other packages or the administrator).
Configuration Item Dir::Etc::TrustedParts.
/etc/apt/trustdb.gpg
Local trust database of archive keys.
/usr/share/keyrings/ubuntu-archive-keyring.gpg
Keyring of Ubuntu archive trusted keys.
/usr/share/keyrings/ubuntu-archive-removed-keys.gpg
Keyring of Ubuntu archive removed trusted keys.
