But now since the challenge fails I don’t know how to install certificates for multiple domains on a single server. I’m aware of the workaround command, but I’m not sure how to adapt it in the manner above (I’m a complete beginner sys admin).
I have installed certbot via its PPA repostiroty (ppa:certbot/certbot), i’m using apache2 with Ubuntu 16.04. The version of certbot in that repository is 0.19. Also does anybody knows when the repository receives updates?
Unfortunately this will take some time, as it requires a release from the debian and ubuntu maintainers.
Until then users should use certbot-auto if they require features from the 0.21.0 release
You could try use certbot-auto in the meantime, or perhaps show us what workaround command you have tried and we can try work through it with 0.19.
Thanks for the replay. I haven’t tried the official workaround because I’m afraid I might do something I won’t know how to undo (I’m complete noob to sys administration).
Certainly, you can just add --dry-run to the end of that last command, and it will use the Let’s Encrypt test CA and not make any changes to your Apache configuration.
