Many Thanks Juri,
The quickfix works although it could not verify 2 signatures:
gpg: key E1F958385BFE2B6E: 2 signatures not checked due to missing keys
gpg: key E1F958385BFE2B6E: public key "X2go Debian/Ubuntu Packaging debian@x2go.org<mailto:debian@x2go.org>" imported
gpg: Total number processed: 1
gpg: imported: 1
Do you think this can lead to a security issue due to the 2 signatures not checked?
Best Regards, Saion

Hello Saion,
as a quickfix you can use another gpg server: apt-key adv --recv-keys --keyserver keyserver.ubuntu.com E1F958385BFE2B6E
On debian buster-backports and newer systems you can use extrepo: apt install extrepo && extrepo enable x2go && apt-get update && apt-get install x2goserver
I have changed this in wiki.
