Could Not Resolve Host Mirrorlist.centos.org | Invalid baseurl for repo | etc/profile & resolv.conf

#Error,#Profile,#Resolv Hello friend, Welcome back to my channel. This is troubleshooting tutorial. I have received few queries and understood that there are challenges in setting up docker when you are doing the installation behind a proxy a server. Basically for those who are connected from an enterprise environment, they will have to go through proxy server for installation of docker. Usually you will get error could not retrieve mirror list or invalid base url for repo due to unable to resolve host or proxy. This is basically because you need to set the proxy server and user authentication in the machine so that the download can go through the proxy server. Follow the steps as you see on the screen to fix this issue.
vi /etc/profile
export HTTP_PROXY=username:password@proxyservername:8080
export HTTPS_PROXY=username:password@proxyservername:8080
export http_proxy=username:password@proxyservername:8080
export https_proxy=username:password@proxyservername:8080
vi /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

I am connecting directly through internet broadband connection not proxy. I have done the exact what you have done but still getting the same error. plz provide some resolution. I have been stuck in this.

[@Thetips4you]

Then it's a different issue, your network may have some issue. Check ip address of the machine and check the network connectivity.
