Distributions: Node 8 is installing instead of node 6.x

[srinivasyl]

OS : Ubuntu 18.04
Followed these steps to install node6.x

Using Ubuntu

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
sudo apt-get install -y nodejs

But ended up installing node 8.10.0

on running this command apt policy nodejs
this is what it displays

nodejs:
Installed: (none)
Candidate: 8.10.0~dfsg-2ubuntu0.4
Version table:

Is there any to install node6.x in ubuntu 18.04

I solved it by doing this
Created a file /etc/apt/preferences.d/nodesource and added below lines

Package: nodejs
Pin: origin deb.nodesource.com
Pin-Priority: 600

and installed node6.14.1
