One of the things that more puzzle me with Linux is the package install. Till now I have used commands from terminal that I just copy-and-paste from somewhere and it has worked. However I confess that I don't feel too comfortable just pasting a crazy long command into my terminal. Anyway...
Today I downloaded for the first time an 'autopackage' (Xara LX 0.7). Not knowing exactly what was an 'autopackage' (but able to suppose what it does) I made some research and confirmed that it was what I thought: a package installer (such as Windows MSI?).
I have read that Autopackage should be part of my Ubuntu 12.10 distro, but it is not there. Anywhere.
The autopackage from Xara just show up as a generic file (script shell type) at my downloads folder and if I click twice over that will only open in a text editor. Definitively it is not right. I tried to find Autopackage app to download and install on my Ubuntu but couldn't find it anywhere.
What is the trick here?
