아래와 같은 에러가 뜰 때 

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

 

그냥 아래 명령어 치고 다시 yum update하니깐 됐다.ㅎ
