[lubosmj]

Version
2.15+

Describe the bug
Users cannot sync the gcr.io/library/busybox repository.

To Reproduce

pulp container remote create --name test --upstream-name library/busybox --url https://mirror.gcr.io
pulp container repository create --name test
pulp container repository sync --name test --remote test

i'm afraid this should be reproducible also on 2.14 branch because this fix that introduced the issue got backported through 2.14 #1304

strange however why katello says it works on python39-pulp-container-2.14.7-1.el8pc.noarch.rpm?

[lubosmj]

The solution is to add the missing application/vnd.docker.distribution.manifest.v1+prettyjws media type to V2_ACCEPT_HEADERS.
