      Check your network, it seems network issue.. Have you added correct DNS Nameserver entries in /etc/resolv.conf file?

    I got the error
    [root@jp1_redhat ansi]# yum repolist
    Loaded plugins: product-id, rhnplugin, security, subscription-manager
    This system is receiving updates from Red Hat Subscription Management.
    This system is receiving updates from RHN Classic or RHN Satellite.
    Error: xz compression not available
    [root@jp1_redhat ansi]#

    • Ravi Saive says:


      I think you’ve installed non-CentOS version of xz package, first remove it.

      # yum remove xz

      And then re-install from the default repositories as shown.

      # yum install xz

      I hope it will fix this issue…

    • Ravi Saive says:


      Please add the DNS Name Servers in /etc/hosts file, if you don’t know DNS, then you can add following line to this file.

    This no longer works if I enter the commands for installation on CentOS 7.
    # wget
    # rpm -ivh epel-release-7-8.noarch.rpm
    The download works but then when ever I run yum I get this unknown repo message I do not know how to get rid of and I do not have access the the epel repo

    Loaded plugins: fastestmirror, langpacks
    epel/i386/metalink | 40 kB 00:00:00
    Could not parse metalink error was
    No repomd file

    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. 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 be much
    slower). If it is a very temporary problem though, this is often a nice

    yum-config-manager –save –setopt=.skip_if_unavailable=true

    File /var/cache/yum/i386/7/epel/metalink.xml does not exist

    IF Your graph is not showing just change the TIME ZONE under vi /etc/php.ini

    I faced the issue because my system time zone and cacti time is different .
