How To Secure Apache with Let's Encrypt on Ubuntu

can you make it for ngnix? getting code An unexpected error occurred: AttributeError: module ‘acme.challenges’ has no attribute ‘TLSSNI01’

The original Ubuntu 20.04 package have this bugs it did not install the right python3-certbot-nginx

So the only solution for ubuntu (AMD64) are via snap

1. sudo snap install certbot --beta --classic

or

sudo add-apt-repository ppa:ahasenack/certbot-tlssni01-1875471
sudo apt-get update

Thanks to Andreas for making his PPA available temporarily to fixed the problem

I hope this will help people who want to upgrade to 20.04

You can re-run “certbot --apache” so that the script can automatically redirect http to https. In case you originally chose to not auto-configure this.

I can confirm that this works like a charm on Ubuntu 20.04. Simple! Thanks.

Step 3 /etc/apache2/sites-available/your_domain.conf

… ServerName your_domain ServerAlias www.your_domain …

do I need to change the name like this if my domain name is examplesite

/etc/apache2/sites-available/examplesite.conf

… ServerName examplesite ServerAlias www.examplesite …

Thanks a lot, everything works fine. All I had to do was enter sudo a2dissite default-ssl.conf

Fantastic tutorial! Thank you 🤩

Hi, thanks for your guide.

One question, can I follow this guide with a subdomain? So that I don’t have to purchase and maintain another domain name?

Im trying to increase the security of the access of phpmyadmin of my server.

Thanks.

Just do it step by step. Thank you very much!
