Can not install ohpc-gnu12-runtimes on Rocky 8

[devilkingsatan666]

After issuing:
dnf install ohpc-gnu12-runtimes.x86_64
I got the following error:
Error:
Problem: conflicting requests
- nothing provides singularity needed by ohpc-gnu12-runtimes-2.6-7.1.ohpc.2.6.x86_64

Interestingly, I have apptainer version 1.1.4-2.el8 installed on my system.

No idea what's going wrong.

The problem is that the package apptainer from EPEL used to provide the dependency singularity although it is not really singularity. EPEL decided to remove this packaging error https://pagure.io/epel/issue/214. So now, nothing provides singularity in EPEL.

Either EPEL needs to introduce the real singularity package or OpenHPC needs to do a small update to replace the require on singularity with apptainer.

EPEL has singularity-ce-3.10.4-1 available for installlation. Which one will the community choose to be the default one?

This is probably way off base but is singularity-ohpc suitable to be marked as provides singularity? I guess the use of environment modules by that package means maybe not?

A temporary fix seems to be to do:

dnf install -y https://github.com/apptainer/apptainer/releases/download/v1.1.3/apptainer-1.1.3-1.x86_64.rpm

Also - the title of this suggests the problem is narrower than it is - ohpc-base-compute also depends on singularity in v2.6, which means openhpc can't currently be used to create compute nodes without a workaround.

We decided to not ship a copy of singularity because EPEL and LEAP do already ship one. The apptainer/singularity situation seems to be complicated and I do not understand what is happening.

There are a couple of fixes possible. I would just change the meta package to require apptainer on RHEL based clones and it should be fixed.

A temporary fix seems to be to do:

dnf install -y https://github.com/apptainer/apptainer/releases/download/v1.1.3/apptainer-1.1.3-1.x86_64.rpm

Thanks.
