Unable to detect your OS...

Hello all, I have been facing this complication while trying to install Cyberpanel on my server.
All help and suggestions are welcomed.

Below is my config:

Distributor ID: Ubuntu
Description: Ubuntu 20.10
Release: 20.10
Codename: groovy

Here are the scripts I used
Script 1 -

sh <(curl https://cyberpanel.net/install.sh || wget -O - https://cyberpanel.net/install.sh)
Script 2 -

cd /tmp
wget -O installer.sh https://cyberpanel.net/install.sh
chmod +x installer.sh
sh installer.sh

Here is the error I get each time:

bencipherx@django-app:~$ sh <(curl https://cyberpanel.net/install.sh || wget -O - https://cyberpanel.net/install.sh)

CyberPanel is supported on Ubuntu 18.04, CentOS 7.x and CloudLinux 7.x…

Thank you for your response. I used to have UBUNTU 20.04 LTS focal fossil. I never really understood how Linode moved it to 20.10. Also, is it possible to safely downgrade the ubuntu version back to 20.04?
