I've searched in Google and looked in another questions, but still I can't solve this problem! I want to install GNOME-shell theme. So I'm trying to enable user-theme-extension in GNOME tweak tool. But I can't enable it. It has a yellow triangle near it says
"extensions does not support shell version"
What should I do? How can I install GNOME shell themes?

Backing to gnome-tweak, you go to the Theme. You will see a workable function of shell-theme.
