We have just setup a new server on a Debian 8 Jessie VPS. We have the run on Debian 8, newer versions will not run our software. I was trying to install Certbot, using some backport instructions I found, but I get this message: Failed to fetch http://ftp.debian.org/debian/dists/jessie-backports/main/binary-amd64/Packages 404 Not Found.
Is there any way to generate a Letsencrypt certificate on the web? Or can I create one on another machine? It doesn't look like it is doable on Debian 8.
Like I said, this software we run will not run on anything above D8. We are not worried about it not getting security updates. I guess a self-signed cert will have to do.
If Certbot does not meet your needs, or you’d like to try something else, there are many more ACME clients to choose from. Once you’ve chosen ACME client software, see the documentation for that client to proceed.
According to the README file on acme-nginx Github page, that's not the correct file:
Certificate was generated into /etc/ssl/private/letsencrypt-domain.pem
It should be that location? Or the README isn't up to date any longer. But I wouldn't think anything called "self signed" is a Let's Encrypt certificate.
letsencrypt-domain.pem is the certificate and letsencrypt-domain.key is the private key corresponding to that certificate.
