oneiric dev version : need to properly downgrade

[arnaudj]

Hello,

I upgraded to oneiric, a dev version.
(from 10.10 to 11.10)
Not very wise when not done on a vm, agreed.
Would you have a proper depot file for me to be able to downgrade properly?
(I've tried to do some recovery to natty, but... the kernel still specify oneiric, not natty, and many things are not behaving right. sometime no keyboard (being used by the network security keyring), most of the time no menu, ...)

Thank you a lot for your help
Feel free to ask me anything

actually, my source list looks like:

There's no downgrade procedure, other than reinstalling 10.10.
