One of the configured repositories failed (Unknown ),

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

Packages for the previous distribution release still work ).

 

3. Disable the repository, 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

 

4. 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 much

Slower). If it is a very temporary problem though, this is often a nice

Compromise:

 

Yum-config-manager -- save -- setopt = . Skip_if_unavailable = true

 

Cannot find a valid baseurl for repo: base/7/x86_64

 

 

 

This error occurs because/etc/resolv. conf is not configured.

 

Solution: Edit the resolv. conf file and add:

Nameserver 8.8.8.8

Save and exit.
