Snap is Canonical’s attempt to refine the app packaging and delivery mechanism on the Linux platform. The Snap packages enable developers to bring much newer versions of apps to Ubuntu 16.04 LTS. Currently, the list of available snap packages is short, but soon we’ll be able to install more packages through the new snap package manager.
It is possible to install snap packages alongside traditional deb packages. These two packaging formats live comfortably next to one another. ( Read more about it here)
If you are on Ubuntu 16.04 LTS or later, you would already have snap installed on your machine, if you are on earlier version, install snap using following command.
$sudo apt install snapd
If you want to cross check if snap is installed or not, run following command.
~$ sudo apt list snapd [sudo] password for conquistador: Listing... Done snapd/xenial-updates,now 2.34.2 amd64 [installed,automatic] N: There is 1 additional version. Please use the '-a' switch to see it
Check the snap version
$ snap version snap 2.36.1 snapd 2.36.1 series 16 ubuntu 16.04 kernel 4.15.0-39-generic

For some application you might need to use word –classic. I got an error which installing visual studio code (vscode) using snap e.g.
$ sudo snap install vscode [sudo] password for conquistador: error: This revision of snap "vscode" was published using classic confinement and thus may perform arbitrary system changes outside of the security sandbox that snaps are usually confined to, which may put your system at risk. If you understand and want to proceed repeat the command including --classic. $ sudo snap install --classic vscode vscode 1.29.1-1542309157 from Snapcrafters installed
Snap packages are automatically updated, if you want to update any package manually, use following command.
sudo snap refresh <package>
