The Rant

It’s no secret that I am a fan of Ubuntu Linux. BUT.. one of the annoying things about using Ubuntu is trying to set up a network printer on a desktop or workstation. Regarding nearly all administrative tasks under most Linux systems that would require root permissions, Ubuntu has done a nice job of making it possible to operate a system as a “normal” user without elevated privileges, and then easily gain the elevated (root) privileges temporarily assigned to complete some specific administrative task. Ubuntu detects when a user is trying to do something requiring the elevated (root) privileges and pops up a small window asking for the current user’s password to gain the required permission. All the magic happens behind the scene and the user never has to issue a text command. It wasn’t long ago that users would have had to open a command terminal and issue all the instructions by hand. Well.. we’ve come a long way.. With the exception of installing a network printer. For some reason, when installing a printer in Ubuntu, the user is not prompted with the normal su password pop-up that presents itself for all other administrative tasks. Instead, the CUPS system prompts the user for the root password – and under Ubuntu, there is no root password by default meaning that root can not complete any direct action requiring a password. In fact, root can not log directly into the system at all. Fortunately, the solution is fairly easy.

The Solution

Do not try to install a printer from System > Administration > Printing menu. It won’t work. Sure, it will allow you to go through the wizard and give you the false impression that you’re actually accomplishing something – until you reach the point where a driver needs to be installed and you’re prompted for the root password. Instead, go to the Applications > Accessories menu and select Terminal.

Once the terminal window opens, issue the following command

sudo system-config-printer

The next line in the terminal window will ask for your password. Type in your user password and hit enter. If all is correct, the printer setup and configuration window will open with elevated privileges enabled and you can finish installing and setting up your new printer from comfort of an easy to use GUI.

Sample Setup

Lets take a few minutes and walk through the process. In this example, I will be setting up a Dell 1700 Laser Printer in my Home Office. Before you get started, you will need to know a few things about the printer first. Read more…

I’ll admit, I am a fan of Ubuntu. I run it on all my personal and home computers with the exception of one (8 in total) and have nothing to complain about. Now the new version, expected to be released in April 2009, is expected to see improvements in booting and operational speeds. That is always a good thing, but what I don’t understand are the claims that the new OS version, code named “Jaunty Jackalope” will cater to Web Applications and the Cloud (cloud computing). I have not heard of any other company making such claims, and I wonder exactly how they plan to “cater”. As far as I can see, no other details have been discussed. It’s unclear if Canonical will make OS or code changes somehow to improve support for web applications, or just make them more available through the UI.

Change of Plans – As I was writing the above, Something occurred to me.

Some points of interest

• Google uses a custom version of Ubuntu for internal operations.
• Google has generated a lot of Buzz recently about entering the office application market opposite Microsoft.
• Canonical/Ubuntu has made impressive progress bringing an alternative desktop operating system to market and is regarded by some as an acceptable replacement to Microsoft.
• Following the Quote from Mark Shuttleworth himself, it does sound like Canonical and Google have been at least talking about ways to “finalize Jaunty plans”.

  "We will be gathering forces in Mountain View on 8th - 12th December to
  survey the upstream landscape and finalize Jaunty plans, enjoying the
  excellent hospitality of Google and Silicon Valley's abundance of talent
  and innovation." - Mark Shuttleworth

Warning – Pure Speculation Follows:

Is it possible that Canonical’s intention to cater to web apps means teaming up or forming some sort of partnership with Google to use or push Google’s suite of web applications (Google Apps) while providing a competitive operating system to rival Microsoft?
