Unable to update GNOME Application Platform

Hi all, I'm running into an error where GNOME Software application is giving an error for updating GNOME Application Platform. It seems something is messed up and it may have been because I tried to add a repository at some point. Anyone know how I might be able to resolve this. I did see on google that running a flatpak update from terminal seems to work for a little while, but then the issue reappears again some time later. Here is a screenshot of the error I get.

See if this thread helps:

Installation complete.

When this you see everything is fine now.
If not and you get a warning like this:

$ flatpak update
This gave: Warning: Failed to install org.freedesktop.Platform.openh264/x86_64/19.08: Error deploying: While trying to apply extra data: runtime/org.freedesktop.Platform/x86_64/19.08 not installed

Then preform a repair

$flatpak repair
$flatpak install flathub org.freedesktop.Platform/x86_64/19.08
$flatpak update

If it worked then you are good if not then do this:

$flatpak install org.freedesktop.Platform/x86_64/19.08
$flatpak uninstall --unused
$flatpak update

Now it should be fine but to get sure do the install again then you should get a answere that everything is up to date.

$flatpak install org.freedesktop.Platform/x86_64/19.08

Or do the update command and when you see " Nothing to do " then every thing is working now.


$flatpak update
Nothing to do.

Best reboot you Linux and then look if the Gnome massage is gone, and do the Update command to get sure you are fine now "sudo apt-get update && sudo apt-get upgrade"
When it have worked not forget to mark it as [SOLVED]

Have fun
