É um problema com o repositório do YUM para a distribuição real ... Não parece que você tenha um repositório "base", baseado na saída do comando yum repolist
. Eu suponho que você poderia simplesmente baixar também ...
[root@Kitteh ~]# yum repolist
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: xt.lol.net
* epel: mirror.cogentco.com
* extras: xt.lol.net
* update: xt.lol.net
repo id repo name status
base CentOS-6 - Base 6346
epel Extra Packages for Enterprise Linux 6 - x86_64 7858
extras CentOS-6 - Extras 4
rpmforge Red Hat Enterprise 6 - RPMforge.net - dag 4445
update CentOS-6 - Updates 665
... e prova que o GIT é parte do repositório base ...
[root@Kitteh ~]# yum info git
