Satellite6 client in Content View with filters complain about perl module

Solution Unverified - Updated

Environment

  • Red Hat Satellite 6
  • Red Hat Enterprise Linux 8

Issue

  • Having a RHEL8 Host in a Content View with filters
  • many dnf (sub)commands report various problems related to perl modules (usually 5.24, 5.26 or 5.30)

Resolution

In most cases, the errors can be ignored. See root cause for more.

Root Cause

Perl modules in RHEL8 have been bundled in a way that is not fully compatible with Content Views filters logic in Satellite6. As an outcome, Satellite can generate some auxiliary metadata of the modules, that are broken in few ways (depending on filters used). Sometimes also the content delivered in the Content View with the filters does not match filter logic (e.g. filters disallow perl:5.30 module stream, which is still contained in the Content View content).

So far, all such mismatched content can be workarounded from client side (i.e. disabling / not enabling perl:5.30 stream) and "just" various dnf problems reported are displayed. Those are usually harmless and access to expected content (i.e. perl:5.26 module stream) is fully available. Therefore the dnf problems can be ignored.

Red Hat Engineering assessed this problem as WONTFIX (see e.g. This content is not included.here), since it is a high-hanging fruit for less benefit gained.

Diagnostic Steps

Various dnf commands print various Problems, like:
