This is a clone of issue OCPBUGS-60929. The following is the description of the original issue:
—
Description of problem:

    When mirroring a large bundle of Openshift 4.19 and several operators, the oc-mirror pull ended with errors but created the mirror.tar file.

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

    oc-mirror v2 4.20

How reproducible:

    happens every time I run this imagesetconfig

Steps to Reproduce:

    1.Create imagesetconfig
    2.run oc-mirror pull, let it complete
    3. See errors at the end of the run
    

Actual results:

    several operator images failed to pull and mirror.tar was created.

Expected results:

If there are any images that fail to pull, do not create mirror.tar file as it is an incomplete representation of the imagesetconfig.  I would expect if a tar file is created that all images I requested to pull are in the mirror.tar

2025/08/26 21:10:22  [ERROR]  : [Executor] [Worker] some errors occurred during the mirroring.
Please review content/working-dir/logs/mirroring_errors_20250826_192226.txt for a list of mirroring errors.
You may consider:

• removing images or operators that cause the error from the image set config, and retrying
• keeping the image set config (images are mandatory for you), and retrying
• mirroring the failing images manually, if retries also fail.
