Ubuntu 16.04 LTS offers support for "Snap" packages. It's a new way to install applications that does not require the apt-get and dpkg commands that allow you to install .deb applications.
Snaps applications use ".snap" as an extension and look more like storage bins (packages). Snap applications come standalone, include all the libraries they need to function, sandboxed. They will install on their own directory and will not interfere with the rest of your system.
Although there are not many available apps yet let's see how you can install them:
