No keyserver available

May be a very simple fix but I am new to this. I followed the installation instructions on However, when I try to verify the GPG signature using

gpg --keyserver --recv 7C9E68152594688862D62AF62D9AE806EC1592E2

I get the error message as
“gpg: keyserver receive failed: No keyserver available”

Can anyone please help with this?

Same problem here, with the additional drawback that the key file was deleted from the download server.

Same here. The following command from the docs fails - did you found any solution to this?

$ gpg --keyserver --recv 7C9E68152594688862D62AF62D9AE806EC1592E2
gpg: requesting key EC1592E2 from hkp server
