Dear all,

I am sharing a specific key so it's simple and easy to show -

    $ apt-key list

    /etc/apt/trusted.gpg.d/debian-archive-jessie-security-automatic.gpg
    -------------------------------------------------------------------
    pub   rsa4096 2014-11-21 [SC] [expires: 2022-11-19]
          D211 6914 1CEC D440 F2EB  8DDA 9D6D 8F6B C857 C906
    uid           [ unknown] Debian Security Archive Automatic Signing
Key (8/jessie) <ftpmaster@debian.org>

    $ sudo apt-key del D21169141CECD440F2EB8DDA9D6D8F6BC857C906
    [sudo] password for shirish:
    OK

Again running the apt-key list tells me that the key is no longer there.

I tried it with some different keys if using the short keycode for
e.g. if just using the first 8 alphanumeric keys it works, but found
it doesn't.

apt-key is part of apt

    $ dpkg -S /usr/bin/apt-key
    apt: /usr/bin/apt-key


     $ apt-cache policy apt
        apt:
          Installed: 1.8.0
          Candidate: 1.8.0
          Version table:
         *** 1.8.0 990
                990 http://cdn-fastly.deb.debian.org/debian
buster/main amd64 Packages
                500 http://cdn-fastly.deb.debian.org/debian
unstable/main amd64 Packages
                100 /var/lib/dpkg/status


I looked at the Debian [BTS][1] but couldn't find a bug and dunno
whether it's a bug or it's a wishlist feature that I need to file. Can
anybody comment ?

I am not 100% sure I am understanding you correctly, but the short
keyID for a gpg key is the _last_ 8 characters and not the 8 first -
With the key you describe above, the short keyID is C857C906.

This might be the cause of your confusion.

And in addition to this, see
