This is a warning that happens when starting Apache2.
$ sudo service apache2 restart
* Restarting web server apache2 [Wed May 08 11:55:52 2013] [warn] The Alias directive in /etc/phpmyadmin/apache.conf at line 3 will probably never match because it overlaps an earlier Alias.
... waiting [Wed May 08 11:55:54 2013] [warn] The Alias directive in /etc/phpmyadmin/apache.conf at line 3 will probably never match because it overlaps an earlier Alias.
[ OK ]
It is caused because the configuration for phpMyAdmin is loaded 2 times: in /etc/apache2/conf.d/phpmyadmin.conf and /etc/apache2/apache2.conf with an include to /etc/phpmyadmin/apache.conf.
To get rid of this warning just comment out this line in /etc/apache2/apache2.conf:
Include /etc/phpmyadmin/apache.conf


great, thank you!
Thanks so much! Trying to squash a LAMP bug and found the Alias error while I was at it.
