Apt-get install jitsi-meet-tokens basexx problem

I follow up below installation steps on Ubuntu 16.04.6 LTS
but I am getting
Error: Error fetching file: Failed downloading https://github.com/aiq/basexx/archive/v0.4.1.tar.gz - tlsv1 alert protocol version
Failed to install basexx - try installing it manually

Can anybody help me to install tokens?
