Core 20 base snap

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.

The core20 base snap provides a runtime environment based on Ubuntu 20.04 LTS (Focal Fossa).

Other Ubuntu environment base snaps include:
- Core 18: <https://snapcraft.io/core18>
- Core 22: <https://snapcraft.io/core22>
- Core 24: <https://snapcraft.io/core24>

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 core20

Snap developers can use this base in their own snaps by adding the following to the snap's snapcraft.yaml:

 base: core20
