phpmyadmin "Not Found" after install on Apache, Ubuntu

Try this

sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf
sudo a2enconf phpmyadmin.conf
sudo systemctl restart apache2

sudo dpkg-reconfigure -plow phpmyadmin 

Select No when asked to reconfigure the database. Then when asked to choose apache2, make sure to hit space while [ ] apache2 is highlighted. An asterisk should appear between the brackets. Then hit Enter. Phpmyadmin should reconfigure and now http://localhost/phpmyadmin should work. for further detail https://www.howtoforge.com/installing-apache2-with-php5-and-mysql-support-on-ubuntu-13.04-lamp

This issue was resolved thanks to this guide: https://help.ubuntu.com/community/ApacheMySQLPHP#Troubleshooting_Phpmyadmin_.26_mysql-workbench by adding

Include /etc/phpmyadmin/apache.conf

...to the /etc/apache2/apache2.conf file and restarting the service.
