Loaded plugins: amazon-id, rhui-lb, search-disabled-repos Could not retrieve mirrorlist https://None/pulp/mirror/rhui-client-config/rhel/ server/7/x86_64/os error was 14: curl#6 - "Could not resolve host: None; Unknown error" One of the configured repositories failed (Unknown), 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=<repoid> ...
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 <repoid> or subscription-manager repos --disable=<repoid>
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=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64
이딴 오류가 뜨는 경우가 굉장히 파다한데,
dhclient (enter) yum update
하면 해결됩니다.
1. vi /etc/named.conf
: /etc/named.comf 경로의 파일로 들어가줍니다.
사진처럼 바꿔주면 됩니다.
insert모드는 i를 누르면 들어가지며 esc + wq 로 나올 수 있습니다.
