Key server receive failed when installing through PPA (Ubuntu 17.04)

I run the command

sudo add-apt-repository ppa:elewebupd8team/java

I get an error message saying:

gpg: keyserver receive
failed: No keyserver available

I have tried looking up a solution to the problem online, but I couldn't find any solution that worked for me. How do I solve this problem?

Try the manual way,

1. Open terminal and open sources list:

sudo gedit /etc/apt/sources.list

2. Add the lines: Look your ubuntu version and change zesty to yours.

deb http://ppa.launchpad.net/webupd8team/java/ubuntu zesty main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu zesty main

3. Add key:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4E1F8A59

4. Run command:

sudo apt-get update

Now you can install packages from this repo.

This is a template to add any repository from ppa.
