[SOLVED] How to determine difference between my application list and default one in ubuntu

10110111 · 11-04-2009, 04:47 PM

I have used ubuntu for some time, installed&removed many packages, and now i need to determine which packages are removed&installed on my installation, comparing this list to default one.
If i had another machine with just installed ubuntu, it would be just as easy as list installed packages on two machines and then diff these lists. But i don't have another machine to clean install ubuntu on it.
How can i do this without having clean ubuntu installation?

Can you clean install to a virtual machine like qemu?

Do:
dpkg --get-selections

on both an Ubuntu live-CD and in your installation, then use the diff command to compare both.

Thank you both - i will just start LiveCD on QEMU and use dpkg --get-selections command, comparing its output to another machine's output
