FeniCS installation, using Ubuntu to install conda 5.3.0

Hi I am installing FeniCS on windows 10. I downloaded Ubuntu and installed conda through Ubuntu. Once I open the jupyter notebook, I am trying this:

!conda config --add channels conda-forge
!conda install -c conda-forge/label/gcc7 mpmath -y (This process is completed)
!conda install fenics -y

When I do install fenics, I get this error

Solving environment: failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://repo.anaconda.com/pkgs/pro/noarch/repodata.json.bz2 Elapsed: - An HTTP error occurred when trying to retrieve this URL. HTTP errors are often intermittent, and a simple retry will get you on your way.

Before I was just trying to do the following and one of the post suggested adding “!conda install -c conda-forge/label/gcc7 mpmath -y” before installation of fenics:

!conda config --add channels conda-forge
!conda install fenics -y

and I was getting this error:

FileNotFoundError(2, “No such file or directory: ‘/home/fenics/anaconda3/bin/python3.8’”)
Attempting to roll back.

Rolling back transaction: done

FileNotFoundError(2, “No such file or directory: ‘/home/fenics/anaconda3/bin/python3.8’”)

Can anyone help with this and let me know what I am missing. I had followed this video to get to this point:
