Ubuntu Versions – How to Find Installed Ubuntu Version

release-managementversions

I installed some version of Ubuntu on my VMware, but I don't know what version exactly it is. How can I find it out?

Best Answer

Your version of Ubuntu can be determined by opening System Settings and then opening the System Info or Details (from 12.04) section:

This page will also tell you whether you have the 32- or 64-bit version of Ubuntu installed, as well as what processor and graphics you have, the amount of RAM installed, and your disk capacity.

You can get this info from a terminal with the command:

lsb_release -a

[Note: for versions before 11.10, e.g. 11.04 this is not available this way, but see Roland's answer below for workable option (basically use the 'System Monitor' icon instead]
