fondo Failure to set wallpaper on GNOME 40

As per description. Fondo works just fine on Ubuntu 20.04, 20.10 and Fedora 33, however it fails to set selected picture as a wallpaper on Fedora 34 (which has GNOME 40 RC), complaining about some dbus issue (I'll provide more details including screenshots in a couple of hours). In all cases flapak version was used.

I could swear it showed exact dbus endpoint at which fondo was not able to connect, however now it shows error dialog box with just

Error while getting peer-to-peer dbus connection: Could not connect: No such file or directory

Also when running from terminal this error message is logged when trying to set a wallpaper:

AccountServiceProvider.vala:56: Could not connect: No such file or directory

Hope that could help.

P.S. Yes, I know - that's not couple of hours. Sorry about that.

Fondo needs to be updated to use the freedesktop wallpaper portal instead of it's current method to set the wallpaper.

Can confirm this. Using Fedora 34 beta with Gnome 40 (stable)

Great application - thank you!

Just confirmation here on the issue from a different set up.

I can confirm the same issue on archlinux, but I think I noticed the issue a few weeks ago (before gnome40 was installed)

Error while getting peer-to-peer dbus connection: Could not connect: No such file or directory

I also did a flatpak install. I went ahead and uninstalled via flatpak and reinstalled to see if any useful information was provided. No warnings came up - well, one did - but it seems to only be talking about a separate application handbrake.

➜ flatpak install fondo

the issue comes from https://github.com/calo001/fondo/blob/bbdd066014888f5c5de588e2871a59ede0f7a566/src/Configs/AccountServiceProvider.vala#L48 which won't work in a sandboxed mode. I suppose that feature only works on elementary which allows you to set the wallpaper for the login screen

As (at least) of 19.4.2021 ... setting a background works on Fedora 34 BETA Workstation & Fedora 35 Pinephone
