Fred Installation Problems on Ubuntu 22.04

Hello Fred Users, I am having trouble downloading the installation script using: 'wget -O fred-ubuntu-install.sh https://fred.nic.cz/public/media/1568014036/56/'#39;. It produces a 404 error: 'HTTP request sent, awaiting response... 404 Not Found'. On trying to install from source tarballs, adding repositories 'add-apt-repository "deb http://archive.nic.cz/ubuntu $(lsb_release -sc) main"' and 'add-apt-repository "deb http://archive.nic.cz/private $(lsb_release -sc) main"' a "no release file/404" error for the first repo and "is not signed/forbidden" for the latter. Please help on how I can work this out. -- Regards, Denzell Yonah Internet Technician Malawi SDNP Tel: 882 089 166 <tel:882 089 166> | Cell: 888 844 657 <tel:888 824 787> domains(a)registrar.mw <mailto:domains@registrar.mw> http://www.nic.mw | http://www.registrar.mw <http://www.nic.mw | http://www.registrar.mw> P.O.
