Red Hat Satellite 6: Repository or Capsule sync fails with Error: Katello::Errors::Pulp3Error Parsing interrupted: The repository metadata being synced into Pulp is erroneous in a way that makes it ambiguous (duplicate PKGIDs).

Solution Verified - Updated

Environment

  • Red Hat Satellite 6.10+
  • Red Hat Satellite Capsule 6.10+

Issue

  • Repository sync or Capsule sync task fails on Satellite with the following error.

    Error:

Katello::Errors::Pulp3Error

Parsing interrupted: The repository metadata being synced into Pulp is erroneous in a way that makes it ambiguous (duplicate PKGIDs), and therefore we do not allow it to be synced in 'mirror_complete' mode. Please choose a sync policy which does not mirror repository metadata. Please read https://github.com/pulp/pulp_rpm/issues/2402 for more details.

Resolution

  • From the failed task details identify the repository_id: xxx.

  • On Satellite WebUI, change the repository Mirroring Policy From Complete Mirroring to Additive and perform the Advanced Sync with the Optimized option.

    Satellite Web UI → Content →  Products →  <Product Name>  → Find the repository →  Click on the repository Mirroring Policy And select as Additive

  • In case the affected repository is part of a Content View, it might be necessary to republish the CV now.

  • To sync the Capsule with all the content:

    Satellite Web UI →  Infrastructure →  Capsules →  Select the Capsule → Use the drop-down next to Synchronize  → Run Complete Sync

  • If the issue still persists, note the concerned content-view name from relative path from the below command:

    # hammer repository info --id xxx

  • Publish and promote those content views and then perform complete sync for the capsule.

Root Cause

  • Additive Mirroring Policy - Neither the content nor the repodata is mirrored. Thus, only new content added since the last synchronization is added to the local repository and nothing is removed.

Diagnostic Steps

  • Find out the Product and repository name from the failed Task details and identify the repository_id.

   Actions::Pulp3::CapsuleContent::RefreshDistribution
