dpkg-reconfigure<\/strong>\u00a0is a powerful command line tool used to reconfigure an already installed package. It is one of the several tools offered under\u00a0dpkg<\/a>\u00a0\u2013 the core package management system on Debian\/Ubuntu Linux. It works in conjunction with\u00a0debconf<\/strong>, the configuration system for Debian packages. Debconf registers the configuration of all installed packages on your system.<\/p>\n

This tool can actually be used to reconfigure an entire Ubuntu or Debian system installation. Simply provide the name(s) of package(s) to reconfigure, and it will ask a number of configuration questions, in the same way when the package was initially installed on your system.<\/p>\n

It can allow you to retrieve the settings of an installed package, as well as change the current settings of that package as recorded in decconf. A common category of packages you can reconfigure are those whose configurations are determined by questions in the package installation script, usually shown via a graphical interface during the package installation process, for example\u00a0phpmyadmin<\/strong>.<\/p>\n

View Configurations Of Installed Package<\/h3>\n

To view current configurations of an installed package \u201cphpmyadmin<\/strong>\u201c, use the\u00a0debconf-show<\/strong>\u00a0utility as shown.<\/p>\n

$ sudo debconf-show phpmyadmin\r\n<\/pre>\n

Reconfigure Installed Package in Debian and Ubuntu<\/h3>\n
If you have already installed a package, for instance\u00a0phpmyadmin<\/strong>, you can reconfigure it by passing the package name to\u00a0dpkg-reconfigure<\/strong>\u00a0as shown.<\/p>\n
$ sudo dpkg-reconfigure phpmyadmin\r\n<\/pre>\n
Once you have run the command above, you should be able to start reconfiguring\u00a0phpmyadmin<\/strong>\u00a0as shown in the following screenshot. You will be asked a series of questions, select the settings you want and complete the process.<\/p>\n
\n
\"Reinstall<\/a><\/p>\n

\n
\"Configure<\/a><\/p>\n
Configure Web Server for PhpMyAdmin<\/p>\n<\/div>\n
When the\u00a0phpmyadmin<\/strong>\u00a0reconfiguration process is done, you will see the some useful information concerning the new package settings as shown in the following screenshot.<\/p>\n
\n
\"PhpMyAdmin<\/a><\/p>\n
PhpMyAdmin Information<\/p>\n<\/div>\n
There are some useful options which allow you to change its default behavior, we will explain some of the practically useful ones, as follows.<\/p>\n
The\u00a0-f<\/code>\u00a0flag is used to choose the frontend (such as dailog, readline, Gnome, Kde, Editor or noninteractive) to use.<\/p>\n
$ sudo dpkg-reconfigure -f readline phpmyadmin\r\n<\/pre>\n
You can permanently change the default frontend via the\u00a0debconf<\/strong>, by running the following command.<\/p>\n
$ sudo dpkg-reconfigure debconf\r\n<\/pre>\n
Use the\u00a0Up<\/strong>\u00a0and\u00a0Down<\/strong>\u00a0keys to select an option, and press the\u00a0TAB<\/strong>\u00a0key to choose\u00a0Ok<\/strong>\u00a0and press\u00a0Enter<\/strong>.<\/p>\n
\n
\"Change<\/a><\/p>\n
Change dpkg-reconfigure Frontend<\/p>\n<\/div>\n
Also choose which questions to ignore according to priority level, as shown in the screenshot and press\u00a0Enter<\/strong>.<\/p>\n
\n
\"Change<\/a><\/p>\n
Change Debconf Priority<\/p>\n<\/div>\n
To specify the minimum priority of questions that will be displayed, directly from the command line, use the\u00a0-p<\/code>option.<\/p>\n
$ sudo dpkg-reconfigure -p critical phpmyadmin\r\n<\/pre>\n
Some packages may be in an inconsistent or broken state, in such a case, you can use the\u00a0-f<\/code>\u00a0flag to force\u00a0dpkg-reconfigure<\/strong>\u00a0to reconfigure a package. Remember to use this flag with caution!<\/p>\n
$ sudo dpkg-reconfigure -f package_name\r\n<\/pre>\n
For more information, see the\u00a0dpkg-reconfigure<\/strong>\u00a0man page.<\/p>\n
$ man dpkg-reconfigure\r\n<\/pre>\n
