I got a very strange problem and cannot figure out why.
When I run
yum info python-pip command on some CentOS 7 machines, it returns Error: No matching Packages to list. But, I used to install python-pip on without problem until now.
epel repository is enabled:
epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 11,016
Strangely, the same command can run successfully on other CentOS 7 servers and returns the information of the package.
CentOS release: CentOS Linux release 7.2.1511 (Core)
epel-release: 7.6 or 7.8 (I tried both.)
Please someone could explain what is wrong the EPEL repository.
EDIT: The yum command output;
[root@local ~]# yum info python-pip Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * epel: fedora.mirror.serversaustralia.com.au * rpmforge: mirror.ventraip.net.au Error: No matching Packages to list
It may be just because of the package has been pulled out from the repository. But I still don't understand why some servers are able to see and download the package but others not.
I have run through the commands below on both servers and the check-update shows that the epel repository is from fedora.uberglobalmirror.com, which is same on both servers.
yum clean all yum check-update yum info python-pip`
