Hi,

This is because CentOS 7 has reached the end of its life. You need to modify your configuration to use https://vault.centos.org/ instead of the main mirrors. *—*

Dear CentOS Community,

I am experiencing an issue when attempting to install packages using yum on CentOS 7. When I run the command yum install vim -y, I receive the following error message:

Loaded plugins: fastestmirror Determining fastest mirrors Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infr... 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).

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

It seems there is an issue with the baseurl for the repository. I have already checked my network connection and it is working properly. I also tried updating the DNS configuration and clearing the yum cache, but the issue persists.

Could someone please provide guidance on how to resolve this issue or point me to the correct repository configuration? Any help would be greatly appreciated.

Thank you for your assistance.
