Can't disable my Ipv6 in my ubuntu

I'm installing hadoop on my linux right now, so far I've installed and extracted hadoop, and set up my Java Home variable. I'm trying to disable my ipv6, but so far when I tried to save changes, it shows the following:

This is my command:

nano /etcl.systct.conf

Can this command work:

error writing /etc/sysct.conf: permission denied
