Public bug reported:

Environment details:

- OS: Ubuntu 24.04
- Deployment: package based
- glance-api version: 2:30.0.0-0ubuntu1~cloud0

This is a follow-up on the discussion on the mailing list [0].

After our recent upgrade to Epoxy we have troubles uploading images to
Glance:

openstack image create --disk-format iso --file .../opensuse/Leap-16.0-offline-installer-x86_64.install.iso --progress --public test-ebl
[=============================>] 100%
HttpException: 415: Client Error for url: http://controller.domain:9292/v2/images/e23d802e-d927-4f34-ae2d-1d6f54d62066/file, Unsupported Media Type

And in the logs this is reported:

2025-10-11 01:16:56.585 65675 ERROR glance.api.v2.image_data [None
req-086ad005-a455-471a-bb0d-9dfe5e27eacf

default default] Multiple formats detected: iso,gpt:
glance.common.exception.InvalidImageData: Multiple formats detected:
iso,gpt

For now I disabled the check by setting:

[image_format]
require_image_format_match = false

Citing Sean's assumption that this might be a regression:

> so i think this is a regression in glance from the cve fix.

I found similar reports for ironic ([1], [2]) but none for glance.
