The technology of snaps requires few presentations at this time. What is new is the latest version of the utility that allows you to create them, Snapcraft 2.9, Which has recently been updated in the repositories of Ubuntu 16.04 LTS (Great Xerus). Snapcraft is a tool for creating irritable packages, Which are also known as snaps, for the version of Snappy Ubuntu Core, Ubuntu Desktop and Ubuntu Server.
This announcement is important, as it is the first development we have of the tool since its release for Ubuntu 16.04 on April 21. Among the new features it incorporates is the YAML confinement property within the packages themselves snap, Which allows you to choose whether to install the developer mode (devmode) As a limited option or not.
This YAML property is designed to work with packages snap in which they are still in development. Specifying in the snap if it can be run in devmode or if it can be run in a limited way, snapd it will generate an error if someone tries to run outside the established cases.
Another of the new properties that are supported in this version of Snapcraft is epoch, Although still under development, and that allows you to perform snap updates by specifying their location.
Finally, the commands have just been implemented bash underlying behind Snapcraft, Because what’s really behind this tool is a command line utility.
How to install Snapcraft 2.9 on Ubuntu
Snapcraft is now available through major Ubuntu repositories and version 16.04 was not going to be any less. That means if you want to upgrade you can do this by simply launching the graphical utility of Ubuntu Software or by ordering apt (If you get along better with the command line) and do a full system upgrade.
But if you don’t already have Snapcraft on your system and go install for the first time, open the Terminal and run the following commands below:
sudo apt update sudo apt install snapcraft sudo apt install snapcraft-examples
