unknown blob error when i'm trying to push image to Github Package Registry by Actions

Hello experts!

I study Github Actions + Github Package Registry.

I have an error when i’m trying to push image to Github Package Registry by Actions

Login Succeeded
The push refers to repository [docker.pkg.github.com/marley-nodejs/mern-stack-front-to-back-v2.0/client.anketa.info]

Project is opensource, you can check everything.

What is wrong?

Any suggestions?

If i made this topic in not right place, please move it.



I tried example by Chris Patterson.

And this example works for me.



But i still did not solve problem with my project.

I think it might be an issue with Package Registry. I’m seeing the same thing. I reported to GitHub Support, and they seemed to confirm an issue on their end escalated to engineering.

My Example:

It looks like I am getting some new assets on my package page every time I try to push, but the only version that shows is “docker-base-layer” when I should see tags for “latest” and “[MyBuildId]”. https://github.com/collinbarrett/FilterLists/packages/26496

Build Def: https://github.com/collinbarrett/FilterLists/blob/1ed56d3bf3e75e1a6e80993f370a8126067afe3a/azure-pipelines.web.yaml
Build Results: https://dev.azure.com/collinbarrett/FilterLists/_build/results?buildId=1561


I have exactly the same issue with Github Package Repository than @collinbarrett while pushing, only “docker-base-layer” is updated! So it seems that this issue is still not fixed

I have also met this issue. But after I run the task again, everything works fine. Seems it’s a random issue.

Today i received an email “Announcing general availability for GitHub Actions and GitHub Package Registry”.

Clicked here  https://github.com/features/package-registry

On “SignUp for Free Beta”

And tried run with my configs from post 1.

Looks everything works.



Yeah @webmakaka the workflows runs! But, if you get back from the Github Package Registry your just built docker image with the tag latest, which is the one you use to build, do you get the last change? I don’t, it seems that it is the tag docker-base-layer which gets the changes

Forget my last message! It seems that it is working now, at least when I get back the latest image on my local machine, the image got my latest code change. So, it seems that it is my CD action which doesn’t work
