[Bug]: Downloading images and videos does not work

GHTaarn commented 7 months ago

What happened?

Nothing happens when I click the download icon on images or videos in a message thread.

What should have happened?

In previous versions, I would get a dialog box asking where I would like to save the download.

  **Minimize to tray**

  Per the request of the Signal developers, this snap does not use the system
  tray by default. This is disabled by default per the request of the Signal
  developers, because system tray support is not stable. Set to `false`,
  Signal will stop when you close it and will not have a system tray icon.
  You can enable it by running the following command.

      snap set signal-desktop tray-icon=true

merlijn-sebrechts commented 7 months ago

Hmm, it seems the snap can't find the xdg desktop portal. Can you show the output of the following command?

apt search xdg-desktop-portal | grep portal | grep installed

GHTaarn commented 7 months ago

It only produces this:


WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

merlijn-sebrechts commented 7 months ago

Oh, wow, that is not supposed to happen. It seems like you broke part of your desktop. What desktop environment are you using? Regular Ubuntu Gnome or KDE or something?

GHTaarn commented 7 months ago

I am using Ubuntu Mate. Mate desktop. So which packages should be installed? Maybe I can just install them explicitly.

GHTaarn commented 7 months ago

You are right, I get the same problem with Firefox, I can't save from Firefox, something must have broken in my desktop

GHTaarn commented 7 months ago

But Firefox is also a Snap, I do not get the problem with Pluma (my editor) which is a .deb package

merlijn-sebrechts commented 7 months ago

Are you on Matrix to debug this situation quickly? You can contact me on Matrix at merlijn-sebrechts:ubuntu.com or @mesebrec on telegram.

I think it might be fixed by installing sudo apt install ubuntu-mate-desktop.

GHTaarn commented 7 months ago

Thanks for your offer, I will sign up to Telegram and contact you, unfortunately the apt install that you suggested was not enough:

ubuntu-mate-desktop is already the newest version (1.282).

GHTaarn commented 7 months ago

The problem was solved with

sudo apt install xdg-desktop-portal-gtk

I am not sure why this package was missing, but whatever the reason, I do not expect that this is a bug in the signal-desktop snap.

merlijn-sebrechts commented 7 months ago

For future reference, running sudo apt install xdg-desktop-portal-gtk fixed the issue.

If you're running regular Ubuntu Desktop, running sudo apt install xdg-desktop-portal-gnome might also be useful.
