APT-KEY(8) APT APT-KEY(8) NAME
apt-key - APT key management utility SYNOPSIS
apt-key [--keyring filename] [command] [arguments...] 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 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 update Update the local keyring with the archive keyring and remove from the local keyring the archive keys which are no longer valid.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 debian-archive-keyring package in Debian. 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, through 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. /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/debian-archive-keyring.gpg Keyring of Debian archive trusted keys. /usr/share/keyrings/debian-archive-removed-keys.gpg Keyring of Debian archive removed trusted keys.

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
