I had a problem:
Could not retrieve mirrorlist http://mirrorlist.centos.org/release=6&arch=x86_64&repo=os error was 14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'" Error: Cannot find a valid baseurl for repo: base
I've read and tried this suggestion. Our server is remote, we connect to it with
ssh. After issuing
ifdown eth0, the server stopped responding.
My OS is CentOS. How can I fix my problem?
