Question

swapon: /swapfile: swapon failed: Operation not permitted

composer update

Does not run due to low memory on a droplet with 2GB.

But swapon operation is not permitted here: “swapon: /swapfile: swapon failed: Operation not permitted”

Followed https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-18-04 to no avail - cannot enable swap in the last step.

What else can I do to enable swap, even if temporarily?

Thanks!

Hi @avayaphone,

This might be a really long shot however, can you try using sudo

sudo swapon: /swapfile

It should help with your problem. If it still exists, please make sure you have the correct ownership and permission on the swapfile. To do so, type in

sudo chmod 600 /swapfile
