Snappy (package manager)

How Snappy packages are different from Deb

An article from PCWorld. Skype, Spotify, Minecraft, JetBrains Dev Suite, MySQL Workbench, Blender.

  • Applications are no longer installed system-wide. The base Ubuntu operating system is kept securely isolated from applications you install later. Both the base system and Snappy packages are kept as read-only images.
  • Snappy packages can include all the libraries and files they need, so they don’t depend on other packages.
  • An update can never fail, as a package installation could potentially fail and become incomplete with typical Linux packages.
  • Snappy also supports “delta” updates, which means only the changed bits of the package need to be downloaded and installed.
  • Snappy-based Ubuntu systems might be standard.

Snap commands

Some snap commands

  1. snap help

  3. snap list: see a list of installed snap app
  4. snap find queryname: find a snap app. For example snap find browser, snap find media.
  5. snap install appname: install snap apps
  6. snap remove appname: remove snap apps
  7. snap info appname: see more information about a snap app
  8. sudo snap refresh: update a snap app. You actually don't need it since snapd runs in the background and handles updates automatically
