I am unable to install lets encrypt on my DigitalOcean droplet. Here is what happens when I try to add repository:
sudo add-apt-repository ppa:certbot/certbot This is the PPA for packages prepared by Debian Let's Encrypt Team and backported for Ubuntu. Note: Packages are only provided for currently supported Ubuntu releases. More info: https://launchpad.net/~certbot/+archive/ubuntu/certbot Press [ENTER] to continue or Ctrl-c to cancel adding it.

Done E: The repository 'http://ppa.launchpad.net/certbot/certbot/ubuntu focal Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
Server that I am going to use it with is NGINX but this is irrelevant for now.
The VPS is new and just deployed a day ago and updated.
