This question already has an answer here:
Earlier I was using Ubuntu 12.04 LTS.
I followed the below question to upgrade my system Upgrade from 12.04 to 13.04?
But it automatically upgraded to 13.10 and also some times it shows 14.04
When I tried the local terminal (Ctrl+Alt+F2), it showed me "Ubuntu trusty tahr" (developer branch).
How do I switch back to 13.10 or to 13.04?
or how do I disable the developer branch?
