Go with one of the ready to use systems. Flatpak, Snap, AppImage. Snap is largely Ubuntu Ecosystem, Flatpak is independent. AppImage is an option if you do not need/want a Sandbox.

Stay away from Docker and LXC for this use case (graphical applications), they are much more work to get going.

Distrobox

One way or another, if you want to run an application you are gonna need its dependencies (the key is the name)… they may be bundled into an appimage or come as part of flatpak ruintime, or be confined inside a container, or live in the nix store, but they will “bloat” your system anyway.

Learn how to cleanup your system (ie. uninstall all packages that are not needed by others that have been requested explicitly) and live a happy life. Only bother with other solutions if the software (or version) you need isn’t available for your distro.

You can use appimages, more importantly if you make a directory next to the appimage with the name of the appimage + .home the appimage will also set that as its $HOME that way you can also keep the configuration files of the app separated from the host OS.

You can also sandbox appimages with aisap.

There is always firejail which is very “even your mom can use it” in terms of usage.

e.g install it, type cd / && sudo firecfg, then your password and thats it.

Both strange and not, tbh. On one hand, I understand the sentiment; on the other hand, installing more software with its own dependencies to isolate electron’s dependencies, and potentially installing twice those libs both electron and something else on your system depend on seems counterproductive (leaving the security benefits of containerization/sandboxing out of the question here, tho).

Look into Incus (formerly LXC) containers or the various i’m gonna replace traditional packaging formats like AppImage, FlatPak and what not.

I’m thinking of using VM but I’m hoping to find a better solution
