Pop os swap partition blues

I suspect that your /etc/fstab has the wrong uuid for the swap partition. When you re-created the partition, it got a new uuid. I would backup fstab then edit it (in superuser mode) to reflect the new uuid (which you can get from gparted). You could also use /dev/sda3 in fstab but using uuid is preferred.

 

Just in case it helps you, or someone else who lands here from a search:

Identify drives uuid:
sudo blkid

View (edit) fstab:
sudo -i yourtexteditor /etc/fstab

How to create a 2GB swap file on the existing root partition if no swap partition is available (Ubuntu based, Arch is different):

Code:

Ubuntu:
cd /
sudo dd if=/dev/zero of=swapfile bs=1M count=2048

Set permissions:
sudo chmod 600 /swapfile

Format to a swap:
sudo mkswap /swapfile

Turn on the swap file:
sudo swapon /swapfile

Ensure the swap file is turned on automatically at system startup:
sudo -i yourtexteditor /etc/fstab

Add the line below. Save and close:
/swapfile  none  swap  sw  0  0

Check if the system is using it:
cat /proc/meminfo

 

I don't know if you've ssd onboard, but if you don't need swap partition for any purpose, you could disable-it or all swap partiton on disk :

Code:

swapoff -a

or edit fstab and put a # at the start of the UUID swap partition

Code:

vi /etc/fstab

Check

Code:

free -h
