I try to install ros kinetic on a computer with Ubuntu 16.04 LTS. I have followed steps here. But, when I have tried to run the command rosdep update, most of the time I get the following output:

What can I do to resolve this issue?
Things I have Tried:
- Running after switching to root user:
I have entered sudo su command. When I have run the rosdep update command, I got the same result except for this part:
Warning: running 'rosdep update' as root is not recommended.
You should run 'sudo rosdep fix-permissions' and invoke 'rosdep update' again without sudo.
- Switching to another Wifi network:
When I have tried after switching to another network, I got the same output.
- Installing ssl libraries:
I have installed some packages with the command apt-get -y install build-essential nghttp2 libnghttp2-dev libssl-dev as the root user. But, again, I got the same output.
- Installing ca-certificates:
When I have run the command apt-get install ca-certificates as the root user, I have seen that ca-certificates package has been already installed.
- Exporting SSL certificate file path:
When I run the rosdep update command after entering the command export SSL_CERT_FILE=/usr/lib/ssl/certs/ca-certificates.crt, I have seen the same output.
- Adding LD_LIBRARY_PATH to .bashrc:
When I have tried to run the rosdep update command after adding the line export LD_LIBRARY_PATH=/user/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH to .bashrc and sourcing the .bashrc file, I got the same output.
