Administrative privileges.
 

I am trying to install a driver for my lexmark S405 printer. I am useing Ubuntu 10.10, and installing "lexmark-inkjet-legacy-wJRE-1.0-1.i386.deb.sh" in terminal. When I do this I get "this operation requires root (administrative) privileges. Please enter the administrative password below:. And I enter the password I use for everything else which is the admin password. Then I get incorrect password given, please retype.

Any thoughts or help would be great, and yes I am a newbie.

Ubuntu works a little bit differently than standard Linux. The administrator (root) is not directly accessible. Instead you must use the sudo utility to gain administrator privileges on a command by command basis.

So you should run the lexmark-inkjet-legacy-wJRE-1.0-1.i386.deb.sh file as follows:
When it asks you for a password you enter the password of your normal user account.

When you run graphical programs that require administrator privileges such as when you are installing software with Synaptic Package Manager it is actually using a graphical version of sudo to gain administrator privileges. That is why you enter your normal user account password to run these kinds of programs.

I am having this same issue. I am also new to Ubuntu. When I enter the above code all I get is "command not found". Do you have any suggestions?
