I ran this script: https://doganbros.com/index.php/jitsi/jitsi-installation-with-jwt-support-on-ubuntu-18-04-lts/ and I get to the part where it creates the new directory mkdir src && and the directory already exists so the script exits. If I try to pick up from that point forward, I end up with errors. If I try to run each command separately I also end up with error. If I purge everything and reinstall I still get errors, even if I run each command separately from the beginning.
Is there as better way to install Lua and Luarocks?
This is in the interest of getting Lua and JWT installed before running the Jitsi install.
