Hi @rhessinger ,

All Images (image created by Docker CLI or official image) have this issue.

Hi @rhessinger ,

I have tried this, but problem still exists. I tried to update MediaType_Name manually, then I could push image. Is there any other way to solve this problem?

Add that, MediaType_Name of new blob in database is null. Pushing to other docker registry is ok.

Hi @rhessinger,

DockerGarbageCollection and feed cleanup task was both executed, but no help. I still can't push image. Even a 13.3kb image causes a timeout. Is there any other possible reason?

Thanks for your reply, I check my feed and common blob storage is enabled.

Now, in my proget, I can upload and download nuget package, pull docker image, but can not push image(Cancelling nested steps due to timeout). I can't find other related message besides "The blob does not have a media type associated with it". I'm not sure if push failure is related to this. Do you have any idea?

I try to push a image to proget docker feed but failed. I checked proget log, then found message "The blob does not have a media type associated with it. This may be fixed by the feed cleanup task for feed" . I run feed clean up task for this feed, but not working. How can I resolve this?

I run proget in docker, version is 6.0.16.
