In Linux, the apt-key command is used to manage the authentication keys of the APT software package management system. Its primary purpose is to add, remove, and list authentication keys.

Here are some common uses of the apt-key command:

  1. Add authentication key:
  2. Retrieve the key with the specified KEY_ID from the keyserver at keyserver.ubuntu.com using apt-key.
  3. KEY_ID represents the ID of the authentication key to be added.
  4. Delete authentication key.
  5. Delete the apt key with the given KEY_ID.
  6. KEY_ID is the ID of the authentication key to be deleted.
  7. List the added authentication keys:
  8. Show the list of GPG keys.

Please note that the apt-key command needs to be executed with root privileges or using sudo, for example:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key KEY_ID

I hope this helps you!
