[HOWTO] Enable Ubuntu-like “sudo” in Debian Squeeze

In Ubuntu, when you need to run a command as root, you just have to run the command with a preceding “sudo” i.e.

sudo command-to-run

. However, in Debian (and many other Linux) it is may not be set as such by default. To set it as default and to allow the normal user to execute the command as root, just follow the following instructions:

Install Sudo
To install sudo, just run the following commands:

apt-get install sudo gksu

Add yourself to Sudoers list
First to open /etc/sudoers as root in terminal, run the follwing commands:


Now, scroll to the bottom of the file and add the following line:

username ALL=(ALL) ALL

where “username” is the username you use to login to your computer.
Press Ctrl+O followed by ENTER to save /etc/sudoers and you are done.

Hope this helps.

[SOLVED] Unable to get Exclusive Lock Problem While Launching Synaptic, /var/lib/dpkg/lock – open (11 Resource temporarily unavailable) Error

I am using Ubuntu 10.04 Lucid Lynx Alpha and I encountered this while installing ltsp-server. The package being configured was ldm-server.

I was installing an application and Synaptic Package Manager just froze forever while configuring a package. I had to shut it down using sudo killall synaptic. Then, when I tried to launch t again, it would come up with “Unable to get Exclusive Lock” message. When I tried apt-get from Terminal, I got /var/lib/dpkg/lock – open (11 Resource temporarily unavailable).
