E: Package 'snapd' has no installation candidate . Can't install snap package manager

When I'm trying to run

sudo apt install snapd

It shows the error as below:

Reading package lists... DoneBuilding dependency tree... DoneReading state information... DonePackage snapd is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another sourceE: Package 'snapd' has no installation candidate

How to resolve this and install snap store in ubuntu ?

I tried to consult official documentation of snap at :https://snapcraft.io/docs/installing-snap-on-ubuntu

and it says:

Snap is pre-installed and ready to go on all recent releases of Ubuntu.This means, if you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 22.04 LTS (Jammy Jellyfish) and Ubuntu 23.04 (Lunar Lobster), you don’t need to do anything.

But why isn't it in my system then !!
