AWS: Your system is not supported by certbot-auto anymore

Question

Trying to renew letsencript on Amazon Linux 2 using certbot and I get the following message:

Your system is not supported by certbot-auto anymore. Certbot cannot be installed.

I am totally lost and I do not know what to do. I cannot find any exhaustive documentation that gives a solution.

Answer 1

According to https://community.letsencrypt.org/t/certbot-1-9-0-release/135414 :

Changed
certbot-auto was deprecated on all systems except for those based on Debian or RHEL.

And from this website: https://community.letsencrypt.org/t/fail-to-detect-amazon-linux-2-certbot/136140

The best chance to get Certbot working on Amazon Linux 2 is to install the rpm from EPEL as described here: https://aws.amazon.com/blogs/compute/extending-amazon-linux-2-with-epel-and-lets-encrypt/

Answer 2

Here is instructions on how to install certbot on any system: https://certbot.eff.org/instructions

Particularly for Ubuntu 18.04 with Nginx webserver I was able to install certbot using the following commands:

snap install core
snap refresh core
snap install --classic certbot

Then you can run certbot using certbot command

Answer 3

What worked for me was to follow this part from Extending Amazon Linux 2 with EPEL official docs:

cd /tmp
wget -O epel.rpm –nv \
https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install -y ./epel.rpm
sudo yum install python2-certbot-apache.noarch

After that, certbot renew started to work.

Answer 4

We dropped certbot altogether on our amazon linux as we couldn't install snapd. We are using getssl (another acme client) and it is looking good. getssl on github

Answer 5

For Ubuntu 16.04, Let’s Encrypt client (certbot). Reset or set up a new AWS Instance(Linux).

sudo apt install software-properties-common

sudo add-apt-repository ppa:certbot/certbot

sudo apt update

sudo apt install certbot python3-certbot-nginx

To check version number, run

certbot --version

Sample output:

certbot 0.31.0

The below command only works when port 80 is open AWS

sudo certbot --nginx --agree-tos --redirect --uir --hsts --staple-ocsp --must-staple -d www.example.com,example.com --email [email protected]
