Ni!

After installing org.signal.Signal with flatpak, `flatpak run org.signal.Signal` fails with the message below. I tried adding `xdg-utils` (which provides xdg-settings) to my system or my user profile, or to both, to no avail. Any ideas? Anyone has Signal Desktop working on Guix? Thanks! ale .~´

$ flatpak run org.signal.Signal

Note that the directories

'/var/lib/flatpak/exports/share'
'/home/eris/.local/share/flatpak/exports/share'

are not in the search path set by the XDG_DATA_DIRS environment variable, so
applications installed by Flatpak may not appear on your desktop until the
session is restarted.

bug#53134: org.signal.Signal on flatpak can't execvp xdg-settings

[John Kehayias via Bug reports for GNU Guix]

Hello,

I use Signal through Flatpak on a Guix System without any issues. I can't say I have seen this error before. Some general pointers about Flatpak (on Guix at least):

1. Applications should be installed as a user, i.e. with flatpak --user I don't think running them it makes a difference specifying, and probably you would have run into an error or suggestion from flatpak telling you to use --user.

2. To interact with the system (Flatpak is a sandbox) you will likely need an xdg-desktop-portal, probably xdg-desktop-portal-gtk or xdg-desktop-portal-wlr (for Wayland, not sure how the setup for that works though)

3. The first warning you see can be rectified by adding the second path (the first won't exist on Guix Systems) to XDG_DATA_DIRS as it notes (in your .profile or similar), or you can use the script provided by the package in your profile's etc/profile.d/flatpak.sh (I don't think Guix automatically uses scripts in etc/profile.d unlike other distros)

Hope that helps! If you can provide other info like how you installed Signal, guix describe, and so on, that may help too.

John

Thanks John for this answer; I hope it helped Alexandre solving their
flatpak related problem.

Closing.
