Unable to set up keys while installing ROS Kinetic on Ubuntu 16.04 LTS

I follow the instructions from here: http://wiki.ros.org/kinetic/Installation/Ubuntu but in the "set up your keys" step

sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116

i get this:

Executing: /tmp/tmp.uIulXAU9Vn/gpg.1.sh --keyserver
hkp://ha.pool.sks-keyservers.net:80
--recv-key
421C365BD9FF1F717815A3895523BAEEB01FA116
gpg: requesting key B01FA116 from hkp server ha.pool.sks-keyservers.net
?: ha.pool.sks-keyservers.net: Host not found
gpgkeys: HTTP fetch error 7: couldn't connect: Success
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
gpg: keyserver communications error: keyserver unreachable
gpg: keyserver communications error: public key not found
gpg: keyserver receive failed: public key not found

I searched and found many answers but i think none of them solve this problem.
