Since this bug can be reproduced on Ubuntu, Debian, and Fedora, we should set `FLATPAK_FORCE_TEXT_AUTH=1` for all WSL users instead of ignoring its existence. After all, the so-called `graphical prompt` in the flatpak documentation seems to be something unique to GNOME. `WSL_DISTRO_NAME` and `WSL_INTEROP` are both located at https://github.com/microsoft/WSL/blob/master/src/linux/init/util.h .
