from the following URL I have downloaded the YubiHSM SDK https://developers.yubico.com/YubiHSM2/Releases/.
However the other URL says we need to validate the package by downloading the keys which is specified from the following URL:https://developers.yubico.com/Software_Projects/Software_Signing.html
However what is the keyserver do we need to use to download a key?
I will be using the following command to receive a key: gpg --keyserver pgp.mit.edu --recv-keys 70D7145F2F35C4745501829A1B21578FC4686BFE
And the command output is as following: gpg: keyserver receive failed: Server indicated a failure
