Issue title: **SOCA Controller Installation on Ubuntu 24.04 Fails Due to "Unable to Locate Package libpmix3"**

[fbitoo-aneo]

The installation of the Slurm scheduler fails on a SOCA controller running Ubuntu 24.04 because a libpmix3 library does not exist.

Here is the line of code executing this command:

Below are the error logs:
