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 base ' 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).

回答: DNSの設定を,192.168.0.~から、8.8.8.8に変更してyum updateを実行したところ、 実行できました 参考URL https://daichan.club/linux/96 ただ、これはできてるのかどうか正直疑問です。
