No problem, I appreciate you adding the extra detail! FYI, apt-get update and apt update never install new software, they just download new lists of software. So I’m not surprised that update didn’t fix the issue. Both apt-get upgrade and apt upgrade should have fixed the issue; we’ll keep an eye out for similar reports, in case there really is an issue with one of the upgrade variants.
Also it’s worth noting that we’ve already updated https://certbot.eff.org/lets-encrypt/ubuntubionic-apache based on the feedback in this thread. Specifically where it used to say:
$ sudo apt-get install python-certbot-apache
Now it says:
$ sudo apt-get install certbot python-certbot-apache
Which should be more correct. Thanks for your feedback, hopefully you’ve made things a bit easier for everyone else!
