Hi all. I have centos/7 on a VM Virtualbox... I want to install all the openstack python clients (nova, swift etc). I installed *yum install centos-release-openstack-queens * and all good but when I try to install one client I have the following error: yum install python-swiftclient *<SNIP>* Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.infonline.de * extras: mirror.infonline.de * updates: centos.mirrors.psw.services centos-ceph-luminous | 2.9 kB 00:00:00 centos-openstack-queens | 2.9 kB 00:00:00 *http://mirror.centos.org/altarch/7/virt/x86_64/kvm-common/repodata/repomd.xm... <http://mirror.centos.org/altarch/7/virt/x86_64/kvm-common/repodata/repomd.xml>: [Errno 14] HTTP Error 404 - Not Found* Trying other mirror. To address this issue please refer to the below wiki article https://wiki.centos.org/yum-errors *<SNIP>* Now the only way to install the package (or any other) is to disable that repo *yum-config-manager --disable centos-qemu-ev* then I can install the client... Any idea? It looks like *http://mirror.centos.org/altarch/7/virt/x86_64 <http://mirror.centos.org/altarch/7/virt/x86_64> doesn't exist.....* -- *Alfredo*
