[LON-CAPA-admin] Package issues updating to RHEL8

[Raeburn, Stuart]

Mark,

The dnf modularity documentation suggests two ways to avoid "filtered out by modular filtering".

If the mirrored loncapa repo you use is called: OIT_LONCAPA_loncapa_rhel8_x86_64, one option would be to use the following command to install perl-HTML-Parser_loncapa.

dnf --enablerepo=OIT_LONCAPA_loncapa_rhel8_x86_64 --setopt=OIT_LONCAPA_loncapa_rhel8_x86_64.module_hotfixes=true install perl-HTML-Parser_loncapa

Another way would be to add this line below the [OIT_LONCAPA_loncapa_rhel8_x86_64] heading.in your repo file for loncapa (most likely located in /etc/yum.repos.d).:

module_hotfixes=true

and then use:

dnf install LONCAPA-prerequisites

The issue here is that there is a perl-HTML-Parser package (version: 3.72-15) available from the @rhel-8-for-x86_64-appstream-rpms repo, and use of dnf modularity is preventing installation of perl-HTML-Parser_loncapa from your "non-modular" local mirror of the loncapa repo for rhel8 (x86_64).

Note: the standard loncapa.repo repository definition available from install.loncapa.org/versions/redhat/8/loncapa.repo
for the "non-mirrored" repo at install.loncapa.org already contains:

module_hotfixes=true

so  for my RHEL8 VMs if perl-HTML-Parser is already installed, and I use the command:
dnf install perl-HTML-Parser_loncapa, what I see is:

Installing:
perl-HTML-Parser_loncapa
     replacing  perl-HTML-Parser.x86_64 3.72-15.module+el8.3.0+6498+9eecfe51

 Installing       : perl-HTML-Parser_loncapa-3.72-1.0.el8.lc.x86_64
 Obsoleting    : perl-HTML-Parser-3.72-15.module+el8.3.0+6498+9eecfe51.x86_64

which is what I expect.

If the module_hotfixes=true line is missing from the repo definition for your custom OIT_LONCAPA_loncapa_rhel8_x86_64 mirror that would be the explanation for the error you reported.

Subject: [LON-CAPA-admin] Package issues updating to RHEL8

Looking for advice.

With Centos 7 reaching end of life, our servers are being moved to RHEL 8.

The systems group prepping the RHEL 8 machine found the following error with the package
installation. My understanding is that they mirror the LONCAPA repositories locally (thus the
OIT_LONCAPA_loncapa_rhel8_x86_64 repository - OIT is Ohio Information Technology).

The error they get is:

Error:
Problem: package LONCAPA-prerequisites-1-26.1.rhel8.noarch from OIT_LONCAPA_loncapa_rhel8_noarch requires perl-HTML-Parser_loncapa, but none of the providers can be installed
  - cannot install the best candidate for the job
  - package perl-HTML-Parser_loncapa-3.72-1.0.el8.lc.x86_64 from OIT_LONCAPA_loncapa_rhel8_x86_64 is filtered out by modular filtering

Does anyone have any insights or workarounds?

Thanks!
Mark
