How to roll back Ubuntu to a previous version?
I have had nothing but problems with my box since I upgraded to 12.10. I'd like to go back to 12.04 (I had no problems at all) - is this possible?
You can in effect install previous versions of all your packages, as were present in 12.04.
But, I am not sure if downgrading as such is possible.
Your best bet would be to do a complete reinstall.
