How to restore color and sharpness of old photos

[satimis]

Flatpaks will put an icon in the Applications menu, .......

Sorry no.

I found Upscayl on the top bar "Type to search" and add its icon on the left vertical bar, Menu Bar. But it can't start by clicking its icon. It is very strange to me!!! It is the same after rebooting the PC.

Clearly something is wrong somewhere. But it does start from the terminal so you can still try it? I'm interested in hearing what you think of the results it produces.

Do other Flatpaks launch normally? (from an icon).
If Upscayl is the only Flatpak you have, I suggest installing another one to see if the problem exists there too. It's up to you, but woth checking. If you want a suggestion for one, a small and simple app like Blanket might serve as a test. It plays ambient background sounds. You can uninstall after testing.

flatpak install flathub com.rafaelmardojai.Blanket

Note that sudo is not used when installing Flatpaks.

I remember this when I last looked at Gnome, the first install of flatpak needed to restart the session then things behaved as expected.

Then I ran it as:

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=upscayl-run --file-forwarding org.upscayl.Upscayl @@u %U @@

without a session restart, Dennis N already installed flatpakk so it just works for him.

Hi 1fallen2,

Thanks for your advice.

Run your command on Terminal:
$ /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=upscayl-run --file-forwarding org.upscayl.Upscayl @@u %U @@

hanging there.

Still can't find Upscayl window on display.

Right-click Upscayl icon on Menu Bar. It shows

All windows
New window
Remove from Favorites
Show details
Quit

Clicking "All windows" and "New window" without response

Clicking "Show details" please refers to the screenshots attached.

For Reference:

Using Flatpak (documentation)

in particular, see the section:

Running applications
Once an application has been installed, it can be launched using the run command and its application ID:
$ flatpak run org.gimp.GIMP

Remember that Flatpaks are universal applications, so there must be a universal way to run them in any environment. Using a terminal is how. With our Gnome systems, we have menus, docks, searching, and the Application Matrix (or Grid) as additional ways to launch.

Hi Dennis N,

On Internet searching, I found following thread;

Upscayl does not run in Ubuntu 24.04 due to apparmor issue #902
https://github.com/upscayl/upscayl/issues/902

Would it be the same in Ubuntu 22.04?

Well it works here:

Please read Post #18 again.....I just showed it works in 24.04.
That Ticket is very old July we have had 2 apparmor updates since.

Apparmor is not your problem, it is something else on your end.
