Bug: apache2 config test failed (ubuntu)

Certificates where created but installation to apache2 failed on redefinition of FastCgiExternalServer: redefinition of previously defined class

In source codes is this:
> FastCgiExternalServer /var/www/www.example.com/php5.external -socket /var/run/php5-fpm-9001.sock -idle-timeout 86400

and probably your installation try to use copy this conf with same FastCgiExternServer definition! That's not possilbe... that is redefinition of same socked and apache2 config fails, with this errors
