From a Kali Linux installation, snap can be installed directly from the command line:
$ apt update $ apt install snapd
Additionally, enable and start both the snapd and the snapd.apparmor services with the following command:
$ systemctl enable --now snapd apparmor
Finally, either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To test your system, install the hello-world snap and make sure it runs correctly:
$ snap install hello-world hello-world 6.3 from Canonical✓ installed $ hello-world Hello World!
Snap is now installed and ready to go! If you’re using a desktop, a great next step is to install the Snap Store app.
