Importing a content to Satellite raises "This field must be unique." error with 400 error code

Solution Verified - Updated

Environment

Red Hat Satellite 6

Issue

A content import to disconnected Satellite failed in past. Trying to import again, we get HTTP status code: 400 error with response body "This field must be unique.".

Resolution

This is still a bug in Satellite 6.12 and later versions, and it is being tracked under Red Hat Jira This content is not included.SAT-31862.

For a permanent fix:

Upgrade to Sat 6.10.4 (or higher) where the This content is not included.underlying bugzilla is fixed.

For a workaround(Satellite 6.12 and above):

  1. Ensure no import tasks are running.

  2. Define right PULP_CERTS for Satellite version:

  • For Satellite < 6.13:

    PULP_CERTS="--cert /etc/pki/katello/certs/pulp-client.crt --key /etc/pki/katello/private/pulp-client.key"

  • For Satellite >= 6.13:

    PULP_CERTS="--cert /etc/foreman/client_cert.pem --key /etc/foreman/client_key.pem"
  1. Check if there are indeed importers left behind:
# curl $PULP_CERTS https://$(hostname -f)//pulp/api/v3/importers/core/pulp/|json_reformat
  1. Delete all importers:
  PULP_HREFS=$(curl $PULP_CERTS https://$(hostname -f)//pulp/api/v3/importers/core/pulp/|json_reformat |grep pulp_href|cut -d ':' -f 2|tr -d '",')

  for pulp_href in $PULP_HREFS; do curl -X DELETE $PULP_CERTS https://$(hostname -f)$pulp_href; done
  1. Start the import again.

Root Cause

There was a pending pulp importer of the same name, as an orphaned artefact forgotten from the previous unsuccessful import attempt.
