Hi @info2cmep,

You’ll need to remove the ppa repository as it’s out of date if I’m not mistaken. To do so, you can run the following 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

Additionally, if you are looking to install, update certbot, The latest source works just fine and can be installed with a one-liner to install certbot.

curl -o- | bash
