RHEL 7.6

Hello Team,

whenever I am using yum, I am getting error below

https://access.redhat.com/articles/1320623

If above article doesn't help to resolve this issue please open a ticket with Red Hat Support.

One of the configured repositories failed (Red Hat Enterprise Linux 7 Server (RPMs)),

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=rhel-7-server-rpms ...

     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 rhel-7-server-rpms

        or

            subscription-manager repos --disable=rhel-7-server-rpms

     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=rhel-7-server-rpms.skip_if_unavailable=true

failure: repodata/repomd.xml from rhel-7-server-rpms: [Errno 256] No more mirrors to try.

I have checked doc

https://access.redhat.com/solutions/2850911

but it is still not working.

Please advise.

Thanks,
