#### Tool for debugging snap confinement policy violations

Snap developers can use this tool to help them debug and fix policy violations.

Each snap runs confined inside its own sandbox. The policy of each sandbox describes what the application is allowed to do. When an application tries to do something that is not allowed, the system logs a policy violation.

This snap

* watches syslog for such policy violations,
* shows them in a human readable format,
* and makes recommendations for how to solve them.

Run the following command to start watching policy violations.

sudo snappy-debug

If you have dropped messages, try the following command instead.

sudo journalctl --output=short --follow --all | sudo snappy-debug

Note: these commands only show policy violations that happen *after* you run them. So first run one of these commands and then run the snap that you want to debug.

See `snappy-debug --help` for more information about this tool.

## Enable snaps on Ubuntu and install snappy-debug

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.
