uname -a for all information regarding the kernel version,

uname -r for the exact kernel version
lsb_release -afor all information related to the Ubuntu version,

lsb_release -r for the exact version
sudo fdisk -l for partition information with all details.

Not correct `uname -a` return all not just kernel version also `lsb_release -a` return all not only Ubuntu version moreover `sudo fdisk -l` return the block numbers and size and not human readable information – Maythux Mar 06 '14 at 15:01
It's a great answer, however, instead of all the information (-a option switch used in Web-E's answer) you can just get the specific numbers. This is much less confusing for a beginner - For this reason I prefer MrVaykadji and Hadi improvements. – notapatch Apr 14 '14 at 10:02

Kernel version is:

uname -r

Ubuntu release version is:

lsb_release -r

All partition size of the HDD in Terminal

df -ht ext4

replace ext4 with your FS type if it's not so

With respect to the marked as answer post:

Not correct uname -a return all not just kernel version also lsb_release -a return all not only Ubuntu version moreover sudo fdisk -l return the block numbers and size and not human readable information

Open terminal. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.

sudo fdisk -l; uname -a; lsb_release -a

To find the exact distribution, that is Ubuntu 16.04.1 or Ubuntu 16.04.3 you would use

lsb_release -d
