Dear Kile developers

The 2.1 beta1 got a lot of bug :
- tabulator is not good and get bug, the tabulator point is so dull
-can't copy and paste, unless you restart Kile.

So I back to old Kile, 2.0 is the better for me :), but I don't know how to install throught the Terminal or App Center in Ubuntu 9.10.
I use ubuntu 9.10 :D
Thanks
