View Full Version : [ubuntu] [SOLVED] What's my su password?

December 11th, 2008, 05:37 PM
I know... it sounds crazy asking for a password, but I feel I missed something.

I created a user password on installation, which works.

I am able to install some software packages with sudo.

I do not remember anything about a super user password. Is there a default value on a new installation?

I want to create a new directory under /usr, and Ubuntu won't let me.

su is disabled by default in Ubuntu. See log-in-as-root (http://ubuntuforums.org/showthread.php?t=716201).

To make a directory in /usr type

sudo mkdir /usr/dirname

Use sudo instead

sudo mkdir /usr/name

Use your user account password to gain sudo rights.

There is no su password - everything is done with sudo.

To create the directory you can either use the command:

sudo mkdir /usr/DIRECTORY_NAME
or open a file manager as root, eg.:

gksu nautilus
