How to install packages using snap Ubuntu

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

Installation.

sudo snap install <package>

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>

Check list of packages installed on your computer

$ snap list
