I have been doing so many sudo apt-get update/(dist-)upgrade since yesterday and something happend – so that I am confused now whether I am using still beta or the stable version.

How do I figure that out?

Best Answer

Open a terminal(type "gnome-terminal" on the dash) and type lsb_release -a and if the output is:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04 LTS
Release:    14.04
Codename:   trusty

you are running the stable release and if the output is:

Distributor ID: Ubuntu
Description: Ubuntu Trusty Tahr (development branch)
Release: 14.04
Codename: trusty

(see the development branch) you are running the beta version.
