@dave There seems to be something wrong with your setup. tmux is definitely part of the RHEL repos, I believe Ruby is, too.
Docker likely isn't, though. RHEL is a podman shop.
@neverpanic cool beans. Guess I’ll poke our corporate folks and ask them what they did setting these boxes up…
You might be able to check this yourself. Take a look in /etc/yum.repos.d/ to see which repos your system is using. Or maybe on RHEL it's /etc/yum/repos.d?
@jrredho @neverpanic I’m seeing epel, epel-testing, epel-cisco-openh264, and redhat.
Interestingly if I look at lists of available packages on pkgs.org, RHEL9 doesn’t appear to have packages for many of the things I mentioned. There are some other options that indicate possible similarity but they’ve all been fruitless for various reasons.
For example, RHEL9 has no tmux package but it has python3-tmuxp, but that fails due to nothing providing python3.9dist(colorama).
While it sounds like you may have other, deeper, issues with this business, let's sort out the .repo files you did find: If you take a look at epel.repo with, say, less, what does the line that begins with "enable=" show?
Also, I believe that Red Hat have a something for RHEL called "subscription-manager" as a dnf plugin. Maybe look through the documentation for dnf for something like that. The result of that search should yield some questions you can ask you IT dept.
