 **Use the option `--appimage-extract-and-run` or `--appimage-extract` with your AppImage to run them in a container. Alternatively, set `export APPIMAGE_EXTRACT_AND_RUN=1` to your current shell. For controlling PulseAudio, use `pactl` instead of `pacmd` as the latter corrupts the audio system within the container. Use `sudoedit` to edit protected files in the desktop instead of using `sudo` followed by the name of the editor.**

-For `systemd`, `polkit`, FUSE mounts, or other sandboxed application distribution systems, do not use them with containers. You can use them if you add unsafe capabilities to your containers, but it will break the isolation of the containers. This is especially bad if you are using Kubernetes. For controlling PulseAudio, use `pactl` instead of `pacmd` as the latter corrupts the audio system within the container. Because `polkit` does not work, use `sudoedit` to edit protected files with the GUI instead of using `sudo` followed by the name of the editor. There will likely be an alternative way to install the applications, including [Personal Package Archives](https://launchpad.net/ubuntu/+ppas). For some applications, there will be options to disable sandboxing when running or options to extract files before running.
