Tasks: TOP => apipie:cache => environment

This looks peculiar:

We ship version 1.4 of this gem in the foreman software collection. Is it possible this was somehow manually installed on the system?

odd not to knowledge I did install hammer_cli_csv and hammer_cli_katello the previous day but I removed them.

gem uninstall fast_gettext

You have requested to uninstall the gem:
fast_gettext-2.0.2

hammer_cli-2.0.0 depends on fast_gettext (>= 0)
If you remove this gem, these dependencies will not be met.

Hmm, looks like you installed hammer inside the rh-ruby25 scl. Additionally, hammer 2.0 is not compatible with Foreman 1.24, you should use hammer 0.19. How did you install it? there are packages for hammer in the foreman repositories that handle all of the requirements for you.

Thanks, I removed all the hammer gems under scl rh-ruby25.
