RHEL 7 で docker-ce をインストールしようとすると、HTTPS Error 404 - Not Found でインストールに失敗します。
# yum-config-manager --add-repo https://download.docker.com/linux/rhel/docker-ce.repo # yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin https://download.docker.com/linux/rhel/7Server/x86_64/stable/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found Trying other mirror. To address this issue please refer to the below knowledge base article https://access.redhat.com/articles/1320623 If above article doesn't help to resolve this issue please open a ticket with Red Hat Support. One of the configured repositories failed (Docker CE Stable - x86_64), 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. Run the command with the repository temporarily disabled yum --disablerepo=docker-ce-stable ... 4. Disable the repository permanently, 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 docker-ce-stable or subscription-manager repos --disable=docker-ce-stable 5. 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=docker-ce-stable.skip_if_unavailable=true failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try. https://download.docker.com/linux/rhel/7Server/x86_64/stable/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found Uploading Enabled Repositories Report
