A default install of what exactly? What steps can be followed to reproduce this problem? The reason I ask is that Flatpak apps can't run the /usr/bin/xdg-email from the host system, so if your steps to reproduce involve something happening inside a Flatpak app that will run xdg-email from the PATH, a dependency on xdg-utils on the host is not going to have the effect that you're hoping for. Inside a Flatpak app, none of the programs installed from .deb packages in the host's /usr/bin are available. Instead, /usr comes from the Flatpak runtime. If the app wants to be able to run xdg-email, then either the app or its runtime needs to include the same code that is available in Debian's flatpak-xdg-utils package (but, again, installed inside the Flatpak app or runtime, not on the host system, so a dependency on flatpak-xdg-utils on the host would not be helpful). For example, the reference runtime org.freedesktop.Platform contains a /usr/bin/xdg-email executable compiled from the same codebase as Debian's flatpak-xdg-utils package (at least, version 22.08 does, I haven't checked older or newer branches). This means that derived runtimes like org.gnome.Platform//44 also contain that executable. > Since the xdg-email portal requires xdg-utils It does not. It requires any email client on the host system, either installed from a .deb or a Flatpak app (or a Snap app or anything else that participates in the freedesktop.org ecosystem), that registers itself in a .desktop file as a freedesktop.org MIME-type handler for the pseudo-MIME-type "x-scheme-handler/mailto". For example, thunderbird or mutt would be suitable. This is the same thing that xdg-utils requires in order to have the xdg-email executable work, in any desktop environment that doesn't have its own special code path in xdg-utils. Steps to demonstrate this, starting from a virtual machine image produced by autopkgtest-build-qemu, which has no graphical environment installed and should be approximately equivalent to an installation from debian-installer with no tasks enabled: # apt install openbox xdm xorg flatpak mutt xterm # apt purge xdg-utils Package 'xdg-utils' is not installed, so not removed # reboot (GUI: log in to xdm, right-click on background, open a terminal) $ flatpak remote-add --user --if-not-exists flathub flathub https://dl.flathub.org/repo/flathub.flatpakrepo $ flatpak install --user flathub org.freedesktop.Platform//22.08 $ flatpak run org.freedesktop.Platform//22.08 [inside Flatpak app's shell]$ xdg-email nob...@example.com (GUI: a new xterm opens, running mutt) or for a more GUI reproducer, replace the last few steps with: $ flatpak remote-add --user --if-not-exists flathub flathub https://dl.flathub.org/repo/flathub.flatpakrepo $ flatpak install --user flathub com.belmoussaoui.ashpd.demo $ flatpak run com.belmoussaoui.ashpd.demo (GUI: go to Email tab, fill in Addresses: nob...@example.com, click Request) (GUI: a new xterm opens, running mutt) smcv
