You need to know which version you are running right now
There are more than one possibilities to identify which version of Linux you are running
In Kubuntu, Ubuntu and derivates you can have a look at /etc/issue
In my case the output looks like this:
Ubuntu 9.04 \n \l
For a debian system you can have a look at /etc/debian_version. This exists on Kubuntu and Ubuntu to and tells you on wich debian version it is based.
The output will show you just a number. In my case:
Another way to find out is to use the lsb_release command. (a python script)
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 9.04
or you can look at het file /etc/lsb-release:
For a lost resort, you can have a look at your /etc/apt/sources.list which will give you most of the information.
