Execute the following command to open the configuration of your Persistent Storage in the *Text Editor* with administration rights.

<ul>
<li>You need to trust the packages from this repository not to break the
security of your Tails.</li>
<li><i>Dangerzone</i> might stop working in Tails outside of the control of
the Tails team.</li>
</ul>

<h2 id="install">Install the <i>Dangerzone</i> package</h2>

[[Connect to the Tor network.|doc/anonymous_internet/tor]]

Execute the following commands to install the `dangerzone` package and its dependencies.

After the packages are installed, a notification appears to ask if you want to install `dangerzone`, `fuse-overlayfs`, and `uidmap` every time you start Tails in the future.

Choose to **Install Every Time**.

Close the *Console*.

<h2 id="test">Convert a test document</h2>

Choose **Apps&nbsp;▸ Office&nbsp;▸ Dangerzone** to open *Dangerzone*.

When opened for the first time, *Dangerzone* installs its container.

This operation can take several minutes.

After the setup finishes, *Dangerzone* opens.

Click the button **Select suspicious documents**.

Select a simple document to test the conversion process, like an empty *LibreOffice* document or an image.

Converting this first document can also take several minutes. After this
first document, converting other documents will be faster.

<p>If converting fails with the error <span class="code">Unknown error code
'125'</span>, restart Tails and try again.</p>

<p><i>Dangerzone</i> needs a lot of available RAM when running for the first
time. Restarting Tails frees as much RAM as possible.</p>
