Today we will teach you how to fix PYCURL ERROR 6 – “Couldn’t resolve host ‘mirrorlist.centos.org'”. This issue is most commonly encountered when trying to run the yum update command on a CentOS based distro with the following error log:
$ yum update ----------------------------------------------------------- Loading mirror speeds from cached hostfile Error: Cannot find a valid baseurl for repo: base Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock error was 14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'" -----------------------------------------------------------
How to Fix It
To fix the error is quite easy, we just need to add Google Public DNS as a DNS resolver in the /etc/resolv.conf file. Add the following variables at the very bottom line of the /etc/resolv.conf file.
nameserver 8.8.8.8 nameserver 8.8.4.4
Then please try to reboot your server and run the system update command once again using the following command:
$ yum update
