lsb_release -r

All partition size of the HDD in Terminal

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

uname -r

sudo fdisk -l

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
