#11 0.673  One of the configured repositories failed (Unknown),
#11 0.673  and yum doesn't have enough cached data to continue. At this point the only
#11 0.673  safe thing yum can do is fail. There are a few ways to work "fix" this:
#11 0.673 
#11 0.673      1. Contact the upstream for the repository and get them to fix the problem.
#11 0.673 
#11 0.673      2. Reconfigure the baseurl/etc. for the repository, to point to a working
#11 0.673         upstream. This is most often useful if you are using a newer
#11 0.673         distribution release than is supported by the repository (and the
#11 0.673         packages for the previous distribution release still work).
#11 0.673 
#11 0.673      3. Run the command with the repository temporarily disabled
#11 0.673             yum --disablerepo=<repoid> ...
#11 0.673 
#11 0.673      4. Disable the repository permanently, so yum won't use it by default. Yum
#11 0.673         will then just ignore the repository until you permanently enable it
#11 0.673         again or use --enablerepo for temporary usage:
#11 0.673 
#11 0.673             yum-config-manager --disable <repoid>
#11 0.673         or
#11 0.673             subscription-manager repos --disable=<repoid>
#11 0.673 
#11 0.673      5. Configure the failing repository to be skipped, if it is unavailable.
#11 0.673         Note that yum will try to contact the repo. when it runs most commands,
#11 0.673         so will have to try and fail each time (and thus. yum will be be much
#11 0.673         slower). If it is a very temporary problem though, this is often a nice
#11 0.673         compromise:
#11 0.673 
#11 0.673             yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
