Flatpaks also offer a certain degree of “security” by running in what essentially is a sandboxed environment. In other words, the Flatpak-ed applications run in a separate container that maintains some degree of isolation from the system.
That being said, these app bundles also come with a plethora of issues, including a few security risks. Managing these permissions is kind of a hassle otherwise — unless you use a very simple GUI tool to manage it extensively.
Using Flatseal to manage Flatpak permissions properly
Simple GUI interface with built-in toggles
The default Flatpak installation leaves a lot to be desired. While most applications run just fine, you’ll soon run into permissions and path issues down the line. A better way to approach an installation is to manually control the properties and access points of the Flatpak in question.
While it is entirely possible to manage these permissions from the command line, the advantages of a GUI cannot be emphasized enough here. Enter Flatseal, a graphical user interface that manages Flatpak permissions on a per-app basis.
Installing Flatseal was pretty easy, and all I had to do was access it from the AUR. Once ready, Flatseal presents a host of options to pick from. These range from being able to control access points to even changing launch environment variables.
There are two major tweaks that, once again, have a…
