cat /etc/roundcube/debian-db.php

for 16.04

cat /etc/roundcube/debiand-db-roundcube.php

output will be like this :

root@mysterydata# cat /etc/roundcube/debian-db.php
<!--?php 
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/roundcube.conf
## by /usr/sbin/dbconfig-generate-include
##
## by default this file is managed via ucf, so you shouldn't have to
## worry about manual changes being silently discarded.  *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##
$dbuser='roundcube';
$dbpass='m50p2Hp1J23h';
$basepath='';
$dbname='roundcube';
$dbserver='localhost';
$dbport='3306';

apt install nano -y
nano /var/lib/roundcube/config/config.inc.php
