I've just installed gtk2 by typing: sudo apt install gtk2.0,
./configure of one package asked for this gtk2
now I don't need it and I want to remove it, when I type: sudo apt remove gtk2.0, I got:
The following packages will be REMOVED:
flowblade gimp gir1.2-gtk-2.0 gpicview gtk2.0-examples ibus-gtk inkscape kasumi kdenlive

xubuntu-desktop
so it will remove all my xubuntu/xfce environment... wtf?
???
why so
ADDED:
After reboot, the looks of some of my apps have changed, I think some app uses gtk, and because I've changed the version to gtk2, then appearance has changed. I think even better, I like the looks of sliders for instance. But the color scheme is now very bad.
That was an very old packages, I was anyway unable to install it... I think now I should run sudo apt-get install gtk3
