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?

There is generally no way you can revert back to previous Ubuntu release from a newer one.

However to stop getting developer updates, make sure your settings are as follows in Ubuntu Software Center > Edit > Software Sources > Updates tab

  • Important security updates - Enabled
  • Recommended updates - Enabled
  • Pre-released updates - Disabled
  • Unsupported updates - Enabled
