Setup swap partition on Ubuntu

Add swap partition after system installation on Ubuntu

Edit /etc/fstab to add the new swap partition as system swap space.

sudo nano /etc/fstab

Get the UUID of the partition using the command

sudo blkid /dev/<paritionid>


sudo blkid /dev/sda3

Alternative to running above command is by using the preinstalled Disks app.


Add the following line that looks like

UUID=<partition-uuid> none   swap    sw      0       0


UUID=62f379a4-a760-4679-b822-7936d7b628bc none   swap    sw      0       0
