@Qaisar_Azeemi Alright. Few Pointers and you will be able to install on Ubuntu Machine.
Rasa X in the future will be deprecated may be in the coming weeks for the local machines, as it meant for servers only. Ref: Installation Guide
If you want to use Rasa X it will not be able to connect with Github as it only works on the Server installation.
Few pointers for you:
- Create a Fresh environment using Python 3.7 or 3.8.
- Activate the env
- Install Rasa Open source (if there are any dependencies please resolve or share with me)
- Try to install Rasa X 0.39.3 which is more stable.
You can Ref this thread for errors and solutions please only its based on Windows: Rasa X runs with several Errors & Warnings - #2 by nik202
