Ubuntu – How to revert to factory settings


I want to reverse all my Ubuntu modifications and return the system to factory settings. I've installed useless stuff and now I want to uninstall everything I manually installed/factory reset.. Is there a way to do that?

I read this article, Reinstall Ubuntu from command line, and it told me to run this:

sudo dpkg-reconfigure -phigh -a

Then this:

sudo apt-get install -f

But Ubuntu can't figure out even what the first one means. It tells me unknown option -a. If you have another way of reinstalling Ubuntu to factory settings I would love to hear it!

AFAIK, there is no way to "reset" Ubuntu. You can't even do that on Windows 7 unless there is an OEM-provided recovery partition...

Just burn the latest ISO to a DVD and reinstall.

Easiest way, plus you'll get 16.04's new features :)
