Same issue here. Github has changed their key tonight (We updated our RSA SSH host key | The GitHub Blog). Don’t know what we can do to update the key on docker hub…

3

Has anyone managed to make builds work again? Any help would be really appreciated

4

Same problem here at this time

5

We are having the same problem here too

6

We are having the same problem.

7

no one can build containers form github.
How long it “days” it may take to update keys?

After contacting dockerhub support, they advised me to follow the steps provided in github’s blog post: We updated our RSA SSH host key | The GitHub Blog :man_facepalming:

9

Same here :man_facepalming:, but after clarifying that the issue occurs on hub.docker.com they told me:

Our engineers are currently working on a solution and we will get back to you as soon as possible.
Thank you for your patience!

It’s hard to believe that first level support at a company like docker is not aware of such fundamental concepts.

An update from the Docker support:

We have gotten confirmation from our engineering team that the fix has been deployed.
Please let us know if you are still experiencing issues and thank you for your patience!
