Cuda on WSL2 Ubuntu 20.04 -

Hi, I’m following the Getting started with CUDA on WSL2 guide.
I have WSL2 with Ubuntu 20.04.
However, at section 4.2.2 following command throws an error:

sudo apt-get update

Error:

Err:34 https://developer.download.nvidia.com/compute/cuda/repos/<distro>/x86_64  Release
  404  Not Found [IP: 152.199.20.126 443]

E: The repository 'https://developer.download.nvidia.com/compute/cuda/repos/<distro>/x86_64  Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Also, this command:

 curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

does not list any Ubuntu 20.04:

deb https://nvidia.github.io/libnvidia-container/stable/ubuntu18.04/$(ARCH) /
#deb https://nvidia.github.io/libnvidia-container/experimental/ubuntu18.04/$(ARCH) /
deb https://nvidia.github.io/nvidia-container-runtime/stable/ubuntu18.04/$(ARCH) /
#deb https://nvidia.github.io/nvidia-container-runtime/experimental/ubuntu18.04/$(ARCH) /
deb https://nvidia.github.io/nvidia-docker/ubuntu18.04/$(ARCH) /

Something similar with the command to install docker:

curl https://get.docker.com | sh

error:

E: The repository 'https://developer.download.nvidia.com/compute/cuda/repos/<distro>/x86_64  Release' does not have a Release file.

Could anyone help me here?
