Conflict Between Ruby 3.1 and PCS on Rocky Linux

Hello Rocky Linux Community,

I’m encountering an issue with upgrading Ruby on my Rocky Linux system. Specifically, there’s a conflict between Ruby 3.1 and PCS (Pacemaker/Corosync Configuration System).

Currently, PCS is working fine with libruby 3.0. However, due to vulnerabilities in Ruby 3.0, I need to upgrade to Ruby 3.1. The problem arises because PCS seems to require ruby-libs 3.0, which is preventing the upgrade.

Here’s a detailed breakdown of the steps I’ve taken and the issue I’m facing:

  1. Uninstalled PCS: I initially removed PCS from the system to avoid any conflicts during the Ruby upgrade process.
  2. Upgraded Ruby to 3.1: I successfully upgraded Ruby to version 3.1 without any issues.
  3. Reinstalled PCS: Upon attempting to reinstall PCS, I encountered the following dependency error:
    [root@space-000c29c16a7c admin]# rpm -Uvh *.rpm
    warning: git-2.43.5-1.el9_4.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 350d275d: NOKEY
    error: Failed dependencies:
    libruby.so.3.0()(64bit) is needed by pcs-0.11.7-2.el9_4.x86_64
    It looks like pcs with ruby3.1 is not available yet .
    I am looking for advice or a workaround to resolve this dependency conflict. Has anyone else faced a similar issue or does anyone have suggestions on how to proceed? I need to maintain PCS functionality while ensuring that the system is secure with the latest Ruby version.

Any insights or guidance would be greatly appreciated.

Thank you for your support!

OK, but where did you get PCS from, and why are using direct rpm install?

If PCS is built against Ruby 3.0 then you cannot upgrade it. You either have to stick with Ruby 3.0 or find PCS that is built against Ruby 3.1.

Also, had you used corosync or pacemaker by what is available by default in Rocky Linux, it doesn’t even require libruby to be installed. Which you can see below:

[root@rocky9 ~]# dnf install corosync pacemaker --enablerepo=highavailability
