I got rid of the error message on Ubuntu 20.04 by removing the ppa repository. It took me a long time to find out the exact command argument, so this might help others :-). I used the command:

sudo apt-add-repository -r ppa:certbot/certbot

After that, the following commands do not generate any errors:

sudo apt update
sudo apt-get update
