Fixes #6955. This updates the Fedora version used in our test farm tests to Fedora 30. The AMI ID comes from https://alt.fedoraproject.org/cloud/ where it is listed as their standard HVM AMI for the region we use us-east-1 (US East (N. Virginia)). Unfortunately, there were a lot of small changes required for this. The big reason for this is on Fedora, there isn't a Python 2 executable installed. In fact, there's not even an executable named python. It's just python3. Rather than installing another Python in each test, I wrote a script that the test scripts can share to figure out the different paths and names that should be used in their script. (This isn't used in test_sdists.sh because the logic is a little different.) Other changes here worth flagging are: I changed the name of the variable RUN_PYTHON3_TESTS in test_leauto_upgrades.sh to RUN_RHEL6_TESTS. The tests that are run when this variable is set test the upgrade from Python 2 to Python 3 on RHEL 6. I think this new name is much better now that we also have Fedora running Python 3. I made tools/simple_http_server.py work on Python 3. You can see tests passing with these changes at https://travis-ci.com/certbot/certbot/builds/113821476. I also ran test_tests.sh and they passed. * Update to Fedora 30 in test farm tests. Fedora 28 is likely to reach its EOL soon. * Add set_python_envvars.sh. * Fix test_apache2.sh on python3 only distros. * Fix test_leauto_upgrades.sh on python3 systems. * Fix certonly_standalone tests with python3 only * Fix test_sdists.sh on python3 only distros. * Make simple_http_server.py work on Python 3. * add comments
Certbot is part of EFF’s effort to encrypt the entire Internet. Secure communication over the Web relies on HTTPS, which requires the use of a digital certificate that lets browsers verify the identity of web servers (e.g., is that really google.com?). Web servers obtain their certificates from trusted third parties called certificate authorities (CAs). Certbot is an easy-to-use client that fetches a certificate from Let’s Encrypt—an open certificate authority launched by the EFF, Mozilla, and others—and deploys it to a web server.
Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting and maintaining a certificate is. Certbot and Let’s Encrypt can automate away the pain and let you turn on and manage HTTPS with simple commands. Using Certbot and Let's Encrypt is free, so there’s no need to arrange payment.
How you use Certbot depends on the configuration of your web server. The best way to get started is to use our interactive guide. It generates instructions based on your configuration settings. In most cases, you’ll need root or administrator access to your web server to run Certbot.
Certbot is meant to be run directly on your web server, not on your personal computer. If you’re using a hosted service and don’t have direct access to your web server, you might not be able to use Certbot. Check with your hosting provider for documentation about uploading certificates or using certificates issued by Let’s Encrypt.
Certbot is a fully-featured, extensible client for the Let's Encrypt CA (or any other CA that speaks the ACME protocol) that can automate the tasks of obtaining certificates and configuring webservers to use them. This client runs on Unix-based operating systems.
To see the changes made to Certbot between versions please refer to our changelog.
Until May 2016, Certbot was named simply letsencrypt or
letsencrypt-auto, depending on install method. Instructions
on the Internet, and some pieces of the software, may still refer to
this older name.

How to run the client
The easiest way to install and run Certbot is by visiting certbot.eff.org, where you can find the correct instructions for many web server and OS combinations. For more information, see Get Certbot.
Understanding the client in more depth
To understand what the client is doing in detail, it's important to understand the way it uses plugins. Please see the explanation of plugins in the User Guide.

System Requirements
See https://certbot.eff.org/docs/install.html#system-requirements.
Current Features
- Supports multiple web servers:
- apache/2.x
- nginx/0.8.48+
- webroot (adds files to webroot directories in order to prove control of domains and obtain certs)
- standalone (runs its own simple webserver to prove you control a domain)
- other server software via third party plugins
- The private key is generated locally on your system.
- Can talk to the Let's Encrypt CA or optionally to other ACME compliant services.
- Can get domain-validated (DV) certificates.
- Can revoke certificates.
- Adjustable RSA key bit-length (2048 (default), 4096, ...).
- Can optionally install a http -> https redirect, so your site effectively runs https only (Apache only)
- Fully automated.
- Configuration changes are logged and can be reverted.
- Supports an interactive text UI, or can be driven entirely from the command line.
- Free and Open Source Software, made with Python.
