I'm running Ubuntu 14.04.5 LTS

I've run following commands

sudo apt-get update
sudo apt-get install imagemagick
sudo apt-get install php5-imagick
sudo apt-get update

Edited my php.in /etc/php/5.6/apache2/php.ini added following at end of file

extension=imagick.so

After all this

sudo service apache2 restart

But still I'm getting the error and even in php -m it's not showing Imagick.

Using

PHP 5.6.28-2+deb.sury.org~trusty+1 (cli)
