Import an exported snapshot set to the system. The snapshot is imported with a new snapshot ID and can be restored using the restore command.

The abort command attempts to abort a change that still has pending tasks.

The ack command tries to add an assertion to the system assertion database. The assertion may also be a newer revision of a pre-existing assertion that it will replace. To succeed the assertion must be valid, its signature verified with a known public key and the assertion consistent with and its prerequisite in the database.

The advise-snap command searches for and suggests the installation of snaps. If --command is given, it suggests snaps that provide the given command. Otherwise it suggests snaps with the given name.

The create-user command creates a local system user with the username and SSH keys registered on the store account identified by the provided email address. An account can be setup at https://login.ubuntu.com.

The debug command contains a selection of additional sub-commands. Debug commands can be removed without notice and may not work on non-development systems.

The disable command disables a snap. The binaries and services of the snap will no longer be available, but all the data is still available and the snap can easily be enabled again.

The disconnect command disconnects a plug from a slot. It may be called in the following ways: $ snap disconnect <snap>:<plug> <snap>:<slot> Disconnects the specific plug from the specific slot. $ snap disconnect <snap>:<slot or plug> Disconnects everything from the provided plug or slot. The snap name may be omitted for the core snap. When an automatic connection is manually disconnected, its disconnected state is retained after a snap refresh. The --forget flag can be added to the disconnect command to reset this behaviour, and consequently re-enable an automatic reconnection after a snap refresh.

The download command downloads the given snap and its supporting assertions to the current directory with .snap and .assert file extensions, respectively.

The enable command enables a snap that was previously disabled.

The export-key command exports a public key assertion body that may be imported by other systems.

The find command queries the store for available packages. With the --private flag, which requires the user to be logged-in to the store (see 'snap help login'), it instead searches for private snaps that the user has developer access to, either directly or through the store's collaboration feature. A green check mark (given color and unicode support) after a publisher name indicates that the publisher has been verified.

The model command returns the active model assertion information for this device. By default, only the essential model identification information is included in the output, but this can be expanded to include all of an assertion's non-meta headers. The verbose output is presented in a structured, yaml-like format. Similarly, the active serial assertion can be used for the output instead of the model assertion.
