How to run Superbacked on Ubuntu Desktop

Overview

This guide walks through installing dependencies and running Superbacked on Ubuntu Desktop. Superbacked is distributed as AppImage binary — a portable format that requires two dependencies and AppArmor may need to be configured.

Setup guide

Step 1: install dependencies

$ sudo apt install --yes libfuse2 zlib1g-dev
Expand code

Step 2: download Superbacked

Download latest release from superbacked.com/download and optionally verify integrity of release.

Usage guide

Heads-up: Ubuntu Desktop 23.10+ ships with AppArmor restrictions on unprivileged user namespaces that may prevent Superbacked from launching. The cleanest fix is to use Superbacked OS, which comes pre-configured. On regular Ubuntu Desktop, either install an AppArmor profile granting Superbacked the userns capability (preserves Chromium’s sandbox) or run from terminal with --no-sandbox flag (easiest but weakens renderer isolation).

Right-click .AppImage file and select “Run as a program”.
