I am unable to install libgtk-4-dev.
How do I install it.
no duplicate questions were found.
Can you tell us why you want to install GTK 4? Also, what is the error message that shows when you attempt to install it?
It just says package not found
I'm trying to install it so I can use newer widgets like GtkGridView and so on
$ sudo apt install libgtk-4-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libgtk-4-dev
What were to happen if you typed
apt search gtk4
in the terminal?
Note: Installing GTK4 on GNOME 3.38 can break themes, though I'm not sure about that. Regardless, install at your own risk.
Exactly.
The package you are trying to install is a GTK4 Package. You will need to wait for Zorin OS 17 for it to be available on Zorin.
You might try Fedora or Ubuntu 22.04 in the meantime.

I would also suggest Mint to the OP as its interface is similar to Zorin.

Doesn't Mint use Cinnamon as its DE?
How would they look similar?
I read somewhere it would release 2022 but there seems to be no news of it?

Not sure about where it was said 2022... The earliest I ever heard was the end of 2023.
The Base for Zorin OS 17, Ubuntu 22.04 itself was only released in 2022. With all the patching, upgrading and testing; it would be next to impossible to get Zorin OS 17 released later that same exact year.
So I just ended up adding Debian 12 stable repos and I am pretty sure like @Turtle11 said IT WILL BREAK SOME STUFF IN ZORIN, I did it anyway
adding this line to /etc/apt/sources.list:
deb http://ftp.debian.org/debian stable main contrib non-free
has added many packages and updates that weren't there before which is huge help as it now lets me compile programs which I wasn't able to before.
I know this is not a great solution and will probably mess up some stuff but I will try to handle it the best I can.
I will update what all break on my computer.
CHEERS!
You can install gtk4 from source or the flatpak. Both will allow you to develop for gtk4.
If you are doing this to add application support, you should wait for zorin 17. Many parts of Zorin will be affected or broken by libraries newer than their current versions. Those libraries will most likely require jammy version of Ubuntu distros... which will cascade into another one of the "something went wrong" screens.
Thanks this was what I was looking for but I can't compile gtk from source either cause all the other packages linke meson glib and many other are out of date.
So I tried cheating and just changing version numbers in the meson.build but that too made a lot of errors.
So for now I am moving to mint and will com back once Zorin 17 is ready

You may be able to get away with adding the jammy repos, installing only the specific dependencies, then removing those repos. But this may not go as you think as those dependencies may require higher version libraries.
It could go either way.
