I've installed flatpak to install VSCode/Codium to have an usable debugger for a Python project I'm working on. After some time tweaking VSCode/Codium trying to get the debbuger to work, just realized flatpak could be the problem. After another considerable amount of time trying different flatpak permissions, realized this is not a good use of my time. Installed the same packages from snap, and everything worked OK.

Flatpak is far better for applications rather than system tools, e.g., Chrom{e,ium}, due to the sandboxing.

The emacs flatpak is just a long and painful road leading nowhere.
