Rasa x 1.0 fail to install on CentOS

I tried to install Rasa x 1.0 on CentOS 7.7 using REI. The installation fails with the following error:

> Welcome to RASA Ephemeral Installer [REI]

 > Detecting OS...
 >  ✓ CentOS Linux 7 (Core)
 x unknown distribution

I checked the installation script rei.sh and noticed that it contains the following lines:

        elif [[ "${distribution}" =~ "Fedora" ]]; then
           preflight_check
           info "Detecting OS..."
           allgood "found ${distribution}"
           check_install_centos

This part refers to Fedora while Fedora doesn’t appear in the supported OS. Also, the last line calls for check_install_centos but this func is not found in the script. Is it a bug?

Same problem, except i’m using WSL on Windows. Any resolution or things I can try to get this to run?

> Detecting OS...
 >  ✓ Debian GNU/Linux 11 (bullseye)
 x unknown distribution

Are CentOS, Debian just not supported yet? It currently looks like the only platform that RASA X can work on are Ubuntu and MacOS?

If so, please update the documentation in GitHub - RasaHQ/REI: Rasa Ephermal Installer repo. Will save a ton of time and hassle for everyone.
