apt-key: Delete a key from the trusted keystore.
$ apt-key del ${key_id}
try on your machine
The command "apt-key del ${key_id}" is used to delete a GPG (GNU Privacy Guard) key from the system's APT (Advanced Packaging Tool) keyring.
Here's a breakdown of the command:
- "apt-key del": This is the main command that is used to delete a key.
- "${key_id}": This parameter represents the ID of the key that you want to delete. The key ID is a unique identifier associated with each GPG key.
When you execute this command, APT will remove the specified key from its keyring. This can be useful if you no longer trust a particular key or if the key has expired. Deleting a key ensures that packages signed by that key will no longer be considered valid by the APT package manager.
