Above is the error I receive every time I attempt to update Ubuntu. I have Ubuntu from the microsoft store, it's the one with no version listed in the title.Since I can't update, I am also unable to get gcc, make, etc as well. I receive the same error each time.

Any tips or advice is appreciated. Thanks in advance.

UPDATE (May 4 2021):The solution is to type

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

into the terminal. It adds a nameserver (specifically Google's server) so everything can connect and update. Immediately after doing this I was able to successfully update the files and download gcc, make, and other files using sudo apt -get.
