This issue only occurs in the Arm32 tests. Example build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=226631&view=logs&jobId=cd63c7f0-318c-51f3-a785-67f930099f68&j=cd63c7f0-318c-51f3-a785-67f930099f68&t=ba40f016-3ef8-51a5-390d-37da4ad750f7.

This is a change in behavior from the previous released version of the syft image. It started in 0.76.0. Quick fix is to pin the version to anchore/syft:v0.75.0.

I've logged anchore/syft#1708 for the syft side.
