Some GNOME flatpaks left over from Silverblue installer don't work properly in Vauxite

[ali1234]

To reproduce, open a terminal and run xdg-open /usr/share/backgrounds/default.png

Expected result: the image should open in ristretto, the default image viewer for Xfce, which is in the base image.

Actual result: GNOME Image Viewer opens, but cannot open the file.

Opening other types of files with xdg-open seems to work okay, for example the XML file opened in Firefox which had no problem displaying it.

I can go to the Xfce control panel "Default Applications" and change the default for PNG files, like this:

After doing this, xdg-open correctly loads ristretto, which is able to display the file.

Two problems in one here:

1. GNOME Image Viewer shouldn't be installed by default on Xfce. (This will be fixed if/when Vauxite gets its own installer ISO)
2. If it is installed, it should work. (The reason they don't work remains an open question)

Note: xdg-open is the CLI equivalent of double clicking a file in a file manager, so the same thing happens if you try to open the image with Thunar.

By any chance do you have the flatpak org.gnome.eog installed?

Type in flatpak list | grep gnome and it should come up with all of the gnome applications.

I got rid of that same flatpak and the command provided returned Ristretto Image Viewer.

Yes, but I do not understand why. I have never installed any flatpaks on this system.

Example of output.

I mean I don't understand why eog is installed. Presumably it is left over from silverblue default install?

That's indeed the cause, rebasing doesn't uninstall flatpaks (but only if the build instructions are explicitly told to do so? Don't know if that's practical or worth exploring), and while rebasing to Vauxite I uninstalled most of the flatpaks which were included with Silverblue by default.

Yeah, the flatpaks are left over from the Silverblue install. You can uninstall them manually for now. They are not part of the ostree image, so there is nothing that could be done in the build instructions to remove them. I could probably add a justfile to the image and have a script to run the just actions automatically on the first boot after rebasing.
