Snap does not support the electron file picker

[retro486]

I'm testing a suzu.json and I get to the step that prompts for the manual download but when I click the "Choose file" button to select the file the application bails with this output:

(ubports-installer:4459): Gtk-WARNING **: 11:21:38.265: Could not load a pixbuf from /org/gtk/libgtk/icons/16x16/status/image-missing.png.
This may indicate that pixbuf loaders or the mime database could not be found.

I've never seen the /org path before... This is on Ubuntu 20.04.1 LTS x64 using the beta snap package.

Full output with -v flag:

Alright, i expected that. Will look into it asap. Thanks for the detailed report! In the mean time, you can use another package for your testing, those should not be affected.

Confirmed this issue is at least not in the deb x64 package. :+1:

Disabling the file picker for now, as snapped electron does not support it yet. For now, users can enter the path and it'll work.
