Tails

Some software is only available as .snap files, and every time I try to install one of those in Tails, it doesn’t work. I’ve googled a lot and could not find anyone talking about how to install .snap files in Tails.

Since there is a “Install additional software” topic in the documentation, it would make a lot of sense to add a section there talking about how to configure snap correctly for making it work in Tails.

Just installing snap and trying to use it without any special config results in all snap commands returning this error:

<code class="c">
snap find
</code>
