I am trying to install vcstools package as you notice int he following lines:
$ sudo apt-get update $ sudo apt-get install vcstools Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package vcstools
I've read that I need to add a repository for that package which is available at http://packages.ubuntu.com/quantal/science/ with the sudo add-apt-repository command; however, I haven't known how add the package and install it.
I would therefore be delighted if anyone could help me and let me know how you propose to solve these little inconvenience.
