GPG partial match

Dear Jitsi crew!

I’m following this tutorial: https://jitsi.org/blog/new-tutorial-installing-jitsi-meet-on-your-own-linux-server/

And I have a doubt about the GPG key match. I download the key with:

wget https://download.jitsi.org/jitsi-key.gpg.key

And got a key with the following public RSA:

$ gpg jitsi-key.gpg.key
gpg: directory ‘/root/.gnupg’ created
gpg: keybox ‘/root/.gnupg/pubring.kbx’ created
gpg: WARNING: no command supplied. Trying to guess what you mean …
pub rsa4096 2016-06-23 [SC]
66A9CD0595D6AFA247290D3BEF8B479E2DC1389C
uid Jitsi <dev@jitsi.org>
sub rsa4096 2016-06-23 [E]

When I double check with:

gpg --search-keys dev@jitsi.org
gpg: data source: https://192.146.137.141:443
(1) Jitsi dev@jitsi.org
4096 bit RSA key **EF8B479E2DC1389C** , created: 2016-06-23
(2) Jitsi dev@jitsi.org
4096 bit RSA key E57E270828500F4D, created: 2016-06-21, expires: 2021-06-20

Which is a partial match of the RSA key. Does this mean a corruption of the key or is it valid?

Thanks a lot, eager to have my own Jitsi server running!,

Rodrigo
