Sorry, but I don’t understand what the question is. Can you tell more about what you want to do?

Two years ago? Are you sure?

Also why did you add these tags to the topic: swarm, docker-compose?

Yes. Today I faced this issue. I saw it happened 2 years ago. But today I faced the following URL for 404 error.

https://download.docker.com/linux/centos/docker-ce.repo/repodata/repomd.xml

Can you try this?

I was trying to upgrade the docker-ce version to 20.x.x. So I faced this 404 error from the following URL.
https://download.docker.com/linux/centos/docker-ce.repo/repodata/repomd.xml

# yum update docker-ce

Where? Do you have a link?

I don’t know what causes it, but since it would not happen in case of a new installation, you can try to remove the docker-ce repo from your cache and add it again following the official documentation:

@rimelek , Thanks I already tried it. :slight_smile: Let me share the screen output for your verification. The server has the external communication.

 One of the configured repositories failed (download.docker.com),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won't use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable download_docker_package

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=download_docker_package.skip_if_unavailable=true

failure: repodata/repomd.xml from download_docker_package: [Errno 256] No more mirrors to try.

It looks like a yum configuration issue. I rarely use yum, so I am not the best person to tell you what went wrong. On a new Centos it should work.
