Hi @anrey-ne_0903, Is this a new Docker feed you have created? IF so, this may be related to this other post https://forums.inedo.com/topic/3081/a-500-error-occurred-in-d-could-not-find-a-part-of-the-path-var-proget-packages-docker-f1. We currently have a bug that throws an error when pushing to the first feed created in each package type when using the proget Docker image. This will be fixed in ProGet 5.3.17, but that forums post has a manual work around to fix that issue. If this is not the issue, then my next question would be is this a recent upgrade of the proget docker image? Thanks, Rich
