So because of the issues with validation with TLS-SNI-01 following the emails I received from Let’s Encrypt I need Certbot version 0.28 or higher.
I am on version 0.26.1 of Certbot.
On Ubuntu 18.04.1 LTS, I followed the steps on this page to update:
I get the following:
The following packages have been kept back:
certbot lxd lxd-client python3-certbot python3-parsedatetime
And Certbot is still 0.26.1
So how do I solve this with out overriding? I do not want to install software on servers that Ubuntu has held back, as they have a reason for holding back packages.
