after installing phpmy admin :
open the file and
nano /etc/apache2/apache2.conf

Add the following to the bottom of the file:

Include /etc/phpmyadmin/apache.conf

Thanks,

I had the same problem, this fixed it

You need to manually copy it over like this:

sudo cp /etc/phpmyadmin/apache.conf /etc/apache2/conf-enabled/phpmyadmin.conf

I've managed to make it to the login page, but only after restarting apache.
$ sudo systemctl restart apache2.service

If you attempt timkaarsemaker's solution but it doesn't work, try restarting apache2.
