How to rollback ubuntu 12.04 to original state?

Question

linux

At the moment there is no flash drive with which I installed the distribution kit - I can not reinstall it. Didn't do rollback points. But, I managed to make horror with a good distribution kit.
I want to completely demolish everything installed. Is it possible to do this with some command or what is the best way to do this in this situation ???

Answer 1

There is no concept of restore points in Linux. There are full/incremental backups.
It's easier to reinstall cleanly - there will be fewer problems.
Rolling back packages, especially without remembering exactly what you did, is quite difficult.
From personal experience, it's really faster to download the same distribution, roll it to USB, and reinstall the system. Or, again, on DVD.

Answer 2

1. By hand
2. autoremove
