I have been using python-certbot-nginx on my digital ocean droplet for several months.
I received an e-mail saying I needed to take action as certbot will no longer be supporting ACME TLS-SNI-01 domain validation.
Looking at this forum it looks like I need to upgrade to certbot 0.28 but when I go through the installation steps I am told that certbot is already at it’s newest version (0.25.0-2+ubuntu17.10.1+certbot+1).
Looking at the ppa, there doesn’t seem to be a version of python-certbot-nginx for ubuntu 17.
Do I need to upgrade to ubuntu 18 to complete the process or will there be a release of certbot for ubuntu 17 before February 13th when the changes come into effect?
