Unable to install x2Go packages for Debian because the repository archive key is not available.
When I try to bootstrap the repository GPG keys using the docs: https://wiki.x2go.org/doku.php/wiki:repositories:debian
with this command:
apt-key adv --recv-keys --keyserver keys.gnupg.net E1F958385BFE2B6E
Then I receive the following error message:
GPG error: http://packages.x2go.org/debian stretch InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E1F958385BFE2B6E
gpg: keyserver receive failed: No name
It was working fine till last month. Please check if the public key has changed.
I mark this ticket as critical because at the moment we are unable to even install x2Go for new users.
