`gpg --list-keys` does not list my keys

  • 772

I've added a lot of keys to my Ubuntu 20.04 computer and when I issue the gpg --list-keys command in my terminal I only get silent output (ie nothing is returned). sudo gpg --list-keys doesn't list any of my keys either. What am I doing wrong?

    When a user uses gpg or gpg2 to import public keys, the keys are stored in the public keyring that is in ~/.gnugpg by default. If you used apt-key the public keys are stored in individual .gpg files in /etc/apt/trusted.gpg.d/. The following command runs the gpg command without arguments for each gpg file in /etc/apt to cover cases where the name of the folder is different from the default. Gpg guesses what output you want based on the content of the file passed as argument:

    find /etc/apt/ -name \*.gpg | xargs -n 1 gpg

    The following alternative command sets each file as the keyring and ignores the default keyring, this way you can replace the --list-public-keys by --export --armor to export public keys to text format:

    find /etc/apt/trusted.gpg.d/ -type f | \
   xargs -n 1 gpg --no-default-keyring --list-public-keys --keyring
