Just one slight improvement on Jerrin's answer on fixing this error with Ubuntu 18.04 by utilizing $USER variable available in the bash terminal. So you could use the following commands two commands:

sudo apt install qemu-kvm

Add the current user to the kvm group

sudo adduser $USER kvm

Also if you are still having issues, one other problem for me was the way in which I installed Ubuntu. I made the mistake of checking the box during installation for installing 3rd party software which did not play nice with my nvidia graphics card for development. So I reinstalled Ubuntu with this third party software unchecked.

Then after installation, open up Software & Updates and go to the Additional Drivers tab. Select the most up to date proprietary drivers that have also been tested and apply changes. Should restart the machine for the changes to take affect.
