How can I install software offline?
At this moment I have next situation:
I have 2 computers:
First computer with Windows 7 and connection to the internet;
Second computer with latest Ubuntu 11.10 and without connection to the internet.
and, my question next: How in this case I can install new packages on Ubuntu?
Well this is rather a tricky situation if both the systems are remotely located from each other and cannot have network sharing (Internet sharing), And I have a tricky solution to your Problem.
Install Ubuntu 11.10 using Wubi installer on your windows 7 Machine. This way you will not alter your system in anyway.
Then install the following Portable Software Center on the Wubi install of Ubuntu.
Here is a way to install it.

Download the software you need for your original Ubuntu PC & transfer the files using a Pen drive or External Hard Disk and Install. :-)
