Yum failing error 14 no more mirrors

If you encounter [Errno 14] when trying to execute yum commands then you've an out of date cache.

I just booted up a Centos VM it hadn't been used for around 3 months and was trying to install Docker. The VM would throw this and not install items.


[root@dataserver1 ~]# yum install docker
Loaded plugins: fastestmirror, langpacks
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
http://mirror.aarnet.edu.au/pub/centos/7.3.1611/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Trying other mirror.
To address this issue please refer to the below knowledge base article

If above article doesn't help to resolve this issue please create a bug on https://bugs.centos.org/

Trying other mirror.

It's a simple fix simply execute

yum clean all
yum makecache fast

It will rebuild your repo cache and have proper details for latest repo mirrors


See ya round
