Red Hat Satellite or capsule upgrade from version 6.15 to 6.16 fails with dependency for 'python38-*' packages.

Environment

• Red Hat Satellite 6.15
• Red Hat Capsule 6.15

Issue

• When attempting to upgrade Satellite from version 6.15 to 6.16 on systems built with version 6.11 or earlier, a dependency conflict occurs. The upgrade process fails due to outdated packages python38-pytz, python38-cffi, and python38-babel that are no longer required in version 6.16 but are not automatically removed during the upgrade.

• Red Hat Satellite or capsule upgrade to 6.16 fails with:

  Problem 1: python38-pytz-2019.3-4.module+el8.9.0+19598+4a60c7b7.noarch from rhel-8-for-x86_64-appstream-rpms
  Problem 2: problem with installed package python38-babel-2.7.0-11.module+el8.9.0+19598+4a60c7b7.noarch
  

Resolution

• Manually remove the conflicting packages (python38-pytz, python38-cffi, and python38-babel) on RHEL, use the following command:

      # dnf remove python38-pytz python38-cffi python38-babel
  

• Re-run the installer:

      # satellite-maintain upgrade run

Root Cause

• The upgrade process for Satellite from version 6.15 to 6.16 does not automatically remove legacy packages (python38-pytz, python38-cffi, and python38-babel) that are no longer needed in version 6.16. These packages cause dependency conflicts during the upgrade.

Diagnostic Steps

• The Red Hat Satellite or capsule 6.15 upgrade to 6.16 fails with:

  python38-pytz-2019.3-4.module+el8.9.0+19598+4a60c7b7.noarch from rhel-8-for-x86_64-appstream-rpms
  - cannot install the best update candidate for package python38-babel-2.7.0-11.module+el8.9.0+19598+4a60c7b7.noarch

• Package came from older version of Satellite 6.11 repository:

  python38-pytz.noarch                                       2021.3-1.el8pc                               @satellite-6.11-for-rhel-8-x86_64-rpms            
  

• Check if the conflicting packages are installed on the Satellite server:

  # rpm -q python38-pytz python38-cffi python38-babel
