Error: 
 Problem 1: cannot install the best update candidate for package python3-certbot-1.1.0-1.el8.noarch
  - nothing provides python3-mock needed by python3-certbot-1.3.0-3.el8.noarch
  - nothing provides python3.6dist(mock) needed by python3-certbot-1.3.0-3.el8.noarch
 Problem 2: package certbot-1.3.0-3.el8.noarch requires python3-certbot = 1.3.0-3.el8, but none of the providers can be installed
  - cannot install the best update candidate for package certbot-1.1.0-1.el8.noarch
  - nothing provides python3-mock needed by python3-certbot-1.3.0-3.el8.noarch
  - nothing provides python3.6dist(mock) needed by python3-certbot-1.3.0-3.el8.noarch
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)


Expected results:

certbot is updated

Comment 1 Felix Schwarz 2020-04-07 05:21:53 UTC

tldr: You need to enable the PowerTools repo.

Longer explanation:
certbot provides the "certbot.tests" package which contains helper code to ease test writing for certbot plugins. That package is part of the public api and depends on python3-mock. Unfortunately in RHEL 8 python3-mock is not part of the main repositories but only available in the powertools repo (provided by Red Hat, not enabled by default but can be enabled easily).

The EPEL guidelines recommend that EPEL8 users enable this repo ("on CentOS 8 it is recommended to also enable the PowerTools repository since EPEL packages may depend on packages from it"): https://fedoraproject.org/wiki/EPEL#Quickstart

As you can see in the git history of certbot I tried to create a custom subpackage just for certbot.tests but in the end this because pretty complicated so I reverted the change and just shipped the upstream code with fewer modifications.

Sweet! Thank you, I did not read the EPEL instructions properly. I don't mind this being closed.
