Base snaps are a specific type of snap that include libraries and dependencies common to many applications. They provide a consistent and reliable execution environment for the snap packages that use them.
This core base snap additionally includes the snapd binaries, which in later releases are installed separately as the snapd snap. For more details on the snapd snap, see https://snapcraft.io/snapd.
The core base snap provides a runtime environment based on Ubuntu 16.04 ESM (Xenial Xerus).
Other Ubuntu environment base snaps include:
Using a base snap
Base snaps are installed automatically when a snap package requires them. Only one of each type of base snap is ever installed.
Manually removing a base snap may affect the stability of your system.
Building snaps with core
Snap developers can use this base in their own snaps by adding the following to the snap's snapcraft.yaml:
base: core

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Core base snap, simply use the following command:
sudo snap install core
Browse and find snaps from the convenience of your desktop using the snap store snap.
