Postgresql:12 and postgresql:13 module conflict on Red Hat Satellite/Capsule while upgrading from version 6.15 to 6.16

Solution Verified - Updated

Environment

  • Red Hat Satellite 6.15
  • Red Hat Capsule 6.15

Issue

  • The postgresql module conflict on Satellite/Caspule 6.15 when Satellite 6.16 repositories are enabled manually for upgrade.
  • The postgresql module conflict on Satellite/Capsule 6.15 when a custom or third party repository that contains a conflicting version of PostgreSQL is enabled on the Satellite/Capsule server.

Resolution

Case (1): If the issue is encountered when Satellite 6.16 repos are enabled:

  1. Run the following commands on the Satellite server:
# dnf module reset satellite:el8
# dnf module reset postgresql
# dnf module enable postgresql:13
# dnf module enable satellite:el8
  1. In case the error shown in the second block of Diagnostic Steps is encountered, run :
# dnf module disable satellite-capsule:el8

Case (2): If a custom or third party repository that contains a conflicting version of PostgreSQL is enabled on the Satellite/Capsule server:

  1. Disable the custom or third party repository (or repositories if there are more than one):

    # dnf config-manager --set-disabled Custom-repo

  2. Enable the required RHEL 8 AppStream and BaseOS repositories, as this is where the required postgresql:13 module stream is provided:

    # subscription-manager repos --enable rhel-8-for-x86_64-baseos-rpms --enable rhel-8-for-x86_64-appstream-rpms

  3. Clear the old repository metadata and cache so that DNF recalculates the module streams using only the correct, newly enabled repositories:

    # dnf clean all
# rm -rf /var/cache/dnf

Root Cause

  • This happens due to change of postgresql version in Satellite 6.15 and 6.16.
  • The issue of conflicting postgresql version can also occur when a custom or third party repositories are enabled with a conflicting postgresql.

Diagnostic Steps

  • Output of yum repolist -v, dnf module list as well as /var/log/dnf.log shows:

  • If the conflict is not caused by Red Hat satellite repository, look for any custom repositories. They might be the reason for the PostgreSQL conflict.
