Hi

I think the problem is that su requires root password - and that is not
really something that exists in Ubuntu.

Try sudo bash with your own password, and it will work

Not exactly. You just need to set you your password, so:

sudo passwd root

and then use the new password when you use 'su'.

Yes - thanks - you are right. Let me rephrase! That is something that is
often not set up & used in Ubuntu!

su is not enabled by default on Ubuntu.
sudo is, however.
When you want to execute a command as super user you do:
sudo <command>

If you want to open a program as superuser (which, you rarely do):
gksudo <command>

for example, this opens the program "nvidia-settings" as super user:
gksudo nvidia-settings

Ubuntu uses "sudo", while other distros, like Fedora might be set to use
"su", by default.

check out this link:
https://help.ubuntu.com/community/RootSudo
and this:

Hope it helps..

sudo su

Khalid:
click on Applications > Accessories > Terminal; and once there you can tag and drag terminal to your desktop after which to be in root you will need to initiate with "Sudo ,,,, [perhaps 'apt get install (whatever)' " after which you will be prompted to give your password, which lets the operation you are commanding to complete itself.
