I have a server with a self signed certificate and as it is causing troubles lately, I decided to see if certbot has any solution for my Ubuntu 14.04
I found that certbot can be installed via snapd, so I've installed snapd and then installed certbot. Then I generated the certs.
The /etc/letsencrypt/ folder was created and the following lines:
were added to my apache2 config file.
I can see that the same file already had:
So I replaced the last line by:
SSLProtocol TLSv1.1 TLSv1.2 TLSv1.3 but no change in the result.
As a consequence of the error message I was wondering if I could update the openssl from the version I have: OpenSSL 1.0.1f 6 Jan 2014
to a newer one in order to have a Certbot's supported protocol
I am stuck here, since I don't know how to upgrade openssl or the upgrade will break the ubuntu.
Any idea how to overcome this problem?
