خطا هنگام اجرای دستور yum check update

سلام وقت بخیر
من یه مشکلی که دارم اینه که زمانی که از دستور yum check-update استفاده میکنم هیچ کدام از پیکج هام آپدیت نمیشه و خطای زیر داده میشه و زمانی که میخوام وب سرور رو هم تغییر بدم و یک وب سرور دیگه نصب کنم هم باز همین خطا داده میشه

To address this issue please refer to the below wiki article

https://wiki.centos.org/yum-errors

If above article doesn't help to resolve this issue please use https://bugs.centos.org/.

 One of the configured repositories failed (varnishcache_varnish5),
 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=varnishcache_varnish5 ...

     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 varnishcache_varnish5
        or
            subscription-manager repos --disable=varnishcache_varnish5

     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=varnishcache_varnish5.skip_if_unavailable=true

failure: repodata/repomd.xml from varnishcache_varnish5: [Errno 256] No more mirrors to try.
