Swap is a special area on your computer, which the operating system can use as additional RAM. Starting with Ubuntu 17.04, the swap partition was replaced by a swap file. The main advantage of the swap file is easy resizing. Note:  before running the following commands, please make sure you have a backup of your data! In the following example, we’ll extend the swap space available in the /swapfile from 4 GB to 8 GB. Turn off all swap processes 1 sudo swapoff -a 2. Resize the swap 1 sudo dd if = /dev/zero of= /swapfile bs=1G count=8 if = input file of = output file bs = block size count = multiplier of blocks 3. Change permission 1 sudo chmod 600 /swapfile 4. Make the file usable as swap 1 sudo mkswap /swapfile 5. Activate the swap file 1
