summary: Daemon and tooling that enable snap packages
description: |
Install, configure, refresh and remove snap packages. Snaps are
'universal' packages that work across many different Linux systems,
enabling secure distribution of the latest apps and utilities for
cloud, servers, desktops and the internet of things.
Start with 'snap list' to see installed snaps.
adopt-info: snapd
# build-base is needed here for snapcraft to build this snap as with "modern"
# snapcraft
build-base: core22
package-repositories:
- type: apt
ppa: snappy-dev/image
grade: stable
license: GPL-3.0
confinement: strict
# Note that this snap is unusual in that it has no "apps" section.
#
# It is started via re-exec on classic systems and via special
# handling in the core18 snap on Ubuntu Core Systems.
#
# Because snapd itself manages snaps it must currently run totally
# unconfined (even devmode is not enough).
#
# See the comments from jdstrand in
# https://forum.snapcraft.io/t/5547/10
# There is no explicit mechanism for passing parameters/configuration through
# snapcraft at snap build time, so instead the build process looks for (or
# creates) the following stamp files, which influence the build process:
#
# - test-build - created by the CI (or the in-repo test build script), indicates
# a test build with version override to 1337.*
# - fips-build - created by the CI or snapd part 'pull' stage to indicate a
# build with FIPS support
# - fips-build-lp - only created by snapd part 'pull' stage, when the build
# environment has been identified to be LP within the FIPS-CC-STIG project,
# where the snapd snap recipe is named snapd-fips
