 | Web server to reconfigure automatically:                                  |
 |                                                                           |

 |                                                                           |

 +------------------------+ Configuring phpmyadmin +-------------------------+
 |                                                                           |
 | The phpmyadmin package must have a database installed and configured      |
 | before it can be used.  This can be optionally handled with               |
 | dbconfig-common.                                                          |
 |                                                                           |
 | If you are an advanced database administrator and know that you want to   |
 | perform this configuration manually, or if your database has already      |
 | been installed and configured, you should refuse this option.  Details    |
 | on what needs to be done should most likely be provided in                |
 | /usr/share/doc/phpmyadmin.                                                |
 |                                                                           |
 | Otherwise, you should probably choose this option.                        |
 |                                                                           |
 | Configure database for phpmyadmin with dbconfig-common?                   |
 |                                                                           |
 |                    <Yes>                       <No>                       |
 |                                                                           |
