certbot-auto isn’t supported on this operating system any more, so you’ll need to upgrade to a non-EOL operating system or use a different Let’s Encrypt client.
Although Certbot is the first Let’s Encrypt client and is recommended by ISRG, there are around 100 different tools that are capable of requesting certificates from Let’s Encrypt.
