Fixing broken merge list in Ubuntu

Sometime broken merge list poses a barricade on the path of further updates. To fix this problem, the old (flawed) merge list has to be removed first, then a new one has to be created. In Ubuntu 12.04, the following worked for me.

sudo rm /var/lib/apt/lists/* -vf sudo apt-get update

Opening a Terminal Anywhere in Ubuntu

Being able to open a terminal from any location on the file system tree (even when you're logged in on a remote server) is a very useful feature. Installing nautilus-open-terminal provides this option in the context menu. To install,

$ sudo apt-get install nautilus-open-terminal

Natuilus file system needs to be reset after installation. To do so,

$ nautilus -q

Right click to bring up the context menu and be happy to see the 'Opne in terminal' option :)
