RELATED: What's New in Ubuntu 20.04 LTS 'Focal Fossa' The Ubuntu Software Center So, with Focal Fossa, Canonical has replaced the Ubuntu Software application with a version that installs snaps by default. What does this mean to you? Therefore, they don’t consider them to be 100 percent “official.” Some people are also wary because snaps aren’t necessarily made by the authors of the software. Snaps have also been criticized for not following the theme of the desktop and their automatic upgrades. Although hard drives are getting bigger and cheaper, traditionalists still balk at the extravagance of each application running in its own mini-container. Launching applications is slower, too. This isn’t the most efficient use of hard drive space. With snaps, every application that needs a particular resource installs its own copy. They also use more hard drive real estate. The downside is the installation files are bigger than the traditional Debian package manager (DEB) files. You can even install multiple versions of the same application, and they won’t cross-pollinate or fight amongst themselves. The application is executed in an encapsulated, ring-fenced way, so its files can’t interfere with those on your computer. This allows the file’s internal SquashFS file system to be accessed. However, it’s at run time that the snap file is mounted on a block loop device. You might expect a snap to be uncompressed and the files extracted at install time. This is what occurs when a new application can’t run either because a required resource isn’t available, it’s the wrong version, or its installation overwrites files required by existing applications so they can’t run. The upside to snaps is they make installations simpler because they avoid the heartache of dependency hell.

The dependents might be library files, web or database servers, or anything else an application must have to launch and run. A snap bundles an application and all its dependents into one compressed file.

“Snap” refers to both the snap command and a snap installation file.
