Satellite sync on Red Hat Satellite 6 fails with " Error retrieving metadata: A connection error occurred:"

Environment

• Red Hat Satellite 6.2.x
• Satellite sync.

Issue

Repository sync fails with below error:

{"code"=>"RPM1004",
      "data"=>{"reason"=>"A connection error occurred"},
      "description"=>"Error retrieving metadata: A connection error occurred",
      "sub_errors"=>[]},
    "_id"=>{"$oid"=>"587ef9f34e0ea39dd625b9df"},
    "id"=>"587ef9f34e0ea39dd625b9df"}],

Resolution

• Make sure there are no paused/pending/running tasks present on satellite server.

• If there are no stuck tasks, you can use Foreman's console to delete any orphaned repositories:

# foreman-rake console

In the foreman-rake console, use these commands:

User.current = User.first

::Katello::Repository.all.each do |repo|
  begin
    puts "Checking #{repo.name} - #{repo.id}"
    Katello.pulp_server.extensions.repository.retrieve_with_details(repo.pulp_id)
  rescue RestClient::ResourceNotFound
    puts "Deleting #{repo.name} - #{repo.id}"
    repo.destroy!
  end
end

• Then run below command to restart the katello-service:

# katello-service restart

2. then re-run the upgrade command as below:

# satellite-installer --scenario satellite --upgrade
