Are you using Ubuntu 20.04? If so, you won’t be able to use the Sury repositories to install or update PHP.

You are right I’m using Ubuntu 20,04, so if I update it to higher version will it damage my vps setup? or it is safe? Thank you sir

Before upgrading, you must backup all your data and conf. If your hosting provider offers a snapshots option, create a snapshot before performing the OS upgrade.

Also, always upgrade to the next version (e.g., from 20.04 to 22.04), never directly from 20.04 to 24.04.

And follow the steps in Hestia doc for that OS upgrade.
