Determining fastest mirrors

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7\&arch=x86_64\&repo=os\&infra=stock error was

14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 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).

  1. Run the command with the repository temporarily disabled

yum --disablerepo=<repoid> ...

  1. 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>

  1. 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
