Install QGIS Dev on Ubuntu or WSL

I am using WSL (Ubuntu 18.04) on win 10 trying to install QGIS Dev.
I tried following the instructions here but got back the following message.

Reading package lists... Done
Building dependency tree
Reading state information... Done        
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created 
or been moved out of Incoming.
The following information may help to resolve the situation:

This is the code I tried running:

sudo apt install gnupg software-properties-commonH
wget -qO - https://qgis.org/downloads/qgis-2020.gpg.key | sudo gpg --no-default-keyring --keyring gnupg-ring:/etc/apt/trusted.gpg.d/qgis-archive.gpg --import
sudo chmod a+r /etc/apt/trusted.gpg.d/qgis-archive.gpg 
sudo add-apt-repository "deb https://qgis.org/debian-nightly `lsb_release -c -s` main"
sudo apt update
sudo apt install qgis qgis-plugin-grass

Am I doing something wrong?
Do I need to use a virtual machine with a GUI instead of using WSL?
