One of the configured repositories failed

Mengatasi error saat proses update server dengan error :  update one of the configured repositories failed 

 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 the
    packages for the previous distribution release still work).

 3. Run the command with the repository temporarily disabled
        yum --disablerepo=<repoid> ...

 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 <repoid>
    or
        subscription-manager repos --disable=<repoid>

 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=<repoid>.skip_if_unavailable=true

Solusinya :

Solusi Pertama :

kita perlu edit /etc/resolv.conf dengan perintah :

vim /etc/resolv.conf

Masukan nameserver

# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 8.8.4.4

Setelah di tambahkan kita save dengan perintah :wq! 

Kemudian jalankan kembali, yum update 

Solusi Kedua :

Hapus  epel release dengan perintah :

yum remove epel-release

Kemudian instal Repo EPEL dengan yang berikut ini (dengan perintah wget):

wget https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-14.noarch.rpm

Kemudian jalankan

rpm -ivh epel-release-7-14.noarch.rpm

Dari sana anda harus dapat melakukan pembaruan yum tanpa masalah.
