centos 7.1 - Fehler-Repository

Hallo, ich habe das minimale Release von CENTOS 7 unter dieser url Verknüpfung heruntergeladen. ISO Centos 7.x herunterladen

Alle funktionieren korrekt ... der PING und das Netzwerk ist in Ordnung. Ich pinge zum Beispiel an einen externen Host.

Aber wenn ich zähle:

[[email protected] ~]# yum update
Loaded plugins: fastestmirror


 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 <repoid>

     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
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

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

Warum?

This is another command:
