How can I use a swap partition instead of a swap file

Question

I have a swap file in my file system /swapfile with 2GB, but I want to use a partition.

I created a partition using Gparted.
I removed my swap file using: sudo swapoff /swapfile
But I have a line on /etc/fstab with my old swapfile.
** I Need To Inform My Ubuntu That I'm Using A Swap Partition. **

How can I achieve this?

@vanadium, My question is the opposite of your suggestion. And I can't achieve my objective reading that another topic. — danilo, Jun 27 '19 at 19:39

I found a solution:

First find the UUID of the swap partition:
sudo blkid | grep 'TYPE="swap"'

Then modify your /etc/fstab and replace /swapfile with UUID=xxx, using the UUID you got from the command above. The line that now has /swapfile must then look something like

UUID=01234567-89ab-cdef-0123-456789abcdef none swap sw 0 0

The swap partition will be used after a reboot or running
sudo swapon -a
