#### A Snap that fails in configurable ways and means

This snap is useful for testing snap hooks.

By setting configuration on the snap, one can control which hooks will fail.

`$ snap set fail-tester HOOK_NAME=true`

e.g.

`$ snap set fail-tester configure=true`

Will cause the configure hook to fail. To undo this, one clears the setting:

`$ snap set fail-tester configure=`

and the configure hook will work again.

Supported hooks are:

* `configure`
* `install`
* `pre-refresh`
* `post-refresh`

## Enable snaps on Ubuntu and install fail-tester

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](https://snapcraft.io/store), an app store with an audience of millions.

### Enable snapd

If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), 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)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), 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.
