Имеется девелоперская подписка rhel.
После регистрации подписки имеем такую ошибку:

To address this issue please refer to the below knowledge base article
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 for Real Time Beta (RHEL 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-rt-beta-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-rt-beta-rpms
subscription-manager repos --disable=rhel-7-server-rt-beta-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
yum-config-manager --save --setopt=rhel-7-server-rt-beta-rpms.skip_if_unavailable=true
failure: repodata/repomd.xml from rhel-7-server-rt-beta-rpms: [Errno 256] No more mirrors to try.
Методы решения описаны в солюшене. Грубо — отключение репозитория rhel-7-server-rt-beta-rpms.
Вот здесь дискуссия:
Вот и ответ guru:
This is a known thing which happens from time to time and was
reported and discussed many times here - simply follow one of
the suggestions and either disable the rt-beta repository
temporarily or permanently by using one of the commands being
provided in the message.
Это нормальное поведение =) ?+
