Could not resolve host: deb.nodesource.com

[devellopah]

I am on linux mint and need 6.x version of node.js so i do

curl -vsL https://deb.nodesource.com/setup_6.x | sudo -E bash -

and get error

* Could not resolve host: deb.nodesource.com
* Closing connection 0

came across #191 i have tried what @ghost had offered.
i have no /etc/apt/sources.list.d/nodesource.list file so i added below lines to /etc/apt/sources.list

deb https://deb.nodesource.com/node_6.x jessie main
deb-src https://deb.nodesource.com/node_6.x jessie main

after that i run sudo apt-get update and get this

W: Failed to fetch https://deb.nodesource.com/node_6.x/dists/jessie/InRelease  Could not resolve host: deb.nodesource.com
W: Some index files failed to download. They have been ignored, or old ones used instead.

So i still cannot fetch repo. Can you figure out what i am doing wrong?
Tell me if i'd better provide some additional information.
Please help.

This looks like a problem with your DNS resolution, not our repository. It's saying that the curl command can't resolve an IP address for deb.nodesource.com. This is what I get when trying to resolve the IP addresses:

bash-3.2$ host deb.nodesource.com
deb.nodesource.com is an alias for d2buw04m05mirl.cloudfront.net.

Which makes sense because the repository is served from a CDN. Until your computer can look up DNS for deb.nodesource.com correctly the repository won't work.
