[login to view URL]: [Errno 14] curl#6 - "Could not resolve host: [login to view URL]; Unknown error" Trying other mirror. One of the configured repositories failed (MySQL 8.0 Community Server - Source), 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=mysql80-community-source ... 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 mysql80-community-source or subscription-manager repos --disable=mysql80-community-source 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=mysql80-community-source.skip_if_unavailable=true failure: repodata/[login to view URL] from mysql80-community-source: [Errno 256] No more mirrors to try.
