How to install root?

Dear Expert,
I am stuck at prerequisites itself.
I was trying to install root so I typed for prerequisite:

                ***sudo apt-get install dpkg-dev cmake g++ gcc binutils libx11-dev libxpm-dev \***

*** libxft-dev libxext-dev python openssl***

But it showing me error again and again.
I was trying to install it in ubuntu app in windows 11. I have the latest version of ubuntu.
I am getting the following error.

Err:2 Index of /ubuntu focal-updates/main amd64 zlib1g-dev amd64 1:1.2.11.dfsg-2ubuntu1.2

That’s why I am not being able to go for the next steps.

Could you please suggest me some solutions ?

Thanks in Advance.
