Description of problem:

Getting the below error when trying to delete a content-view version. Try to clean up the content-view version through API, and hit this issue randomly.

Need to manually skip/resume these tasks to successfully delete the content-view version but getting stuck on below error.


Version-Release number of selected component (if applicable):
6.4


Actual results:

Expected results:

content-view has to get deleted without any error and without going into a paused state.

From the code comments, I can see that it is trying to re-delete the distributor and content but it is obvious that if it is trying to re-delete it will not find the file "/var/lib/pulp/published/yum/https/repos/redhat/content_views/RHEL_7/78.0/content/dist/rhel/server/7/7Server/x86_64/sat-tools/listing".
