02:42:08 One of the configured repositories failed (End Point repository),
02:42:08 and yum doesn't have enough cached data to continue. At this point the only
02:42:08 safe thing yum can do is fail. There are a few ways to work "fix" this:
02:42:08
02:42:08 1. Contact the upstream for the repository and get them to fix the problem.
02:42:08
02:42:08 2. Reconfigure the baseurl/etc. for the repository, to point to a working
02:42:08 upstream. This is most often useful if you are using a newer
02:42:08 distribution release than is supported by the repository (and the
02:42:08 packages for the previous distribution release still work).
02:42:08
02:42:08 3. Run the command with the repository temporarily disabled
02:42:08 yum --disablerepo=endpoint ...
02:42:08
02:42:08 4. Disable the repository permanently, so yum won't use it by default. Yum
02:42:08 will then just ignore the repository until you permanently enable it
02:42:08 again or use --enablerepo for temporary usage:
02:42:08
02:42:08 yum-config-manager --disable endpoint
02:42:08 or
02:42:08 subscription-manager repos --disable=endpoint
02:42:08
02:42:08 5. Configure the failing repository to be skipped, if it is unavailable.
02:42:08 Note that yum will try to contact the repo. when it runs most commands,
02:42:08 so will have to try and fail each time (and thus. yum will be be much
02:42:08 slower). If it is a very temporary problem though, this is often a nice
02:42:08 compromise:
02:42:08
02:42:08 yum-config-manager --save --setopt=endpoint.skip_if_unavailable=true
02:42:08
