How do I find out what version of Ubuntu is installed on my server?
If you would like to know the version of Ubuntu which is installed on your server / vps then log in to a shell via SSH (or open a terminal windows if running a desktop version) and type the following :-
lsb_release -a
This will print the version on Ubuntu you are using, which may look something like this (with different version numbers and build names maybe)
No LSB modules are available.
