I have updated Ubuntu 18.04 over Ubuntu GNOME 16.04.
How to get default GNOME shell theme in Ubuntu 18.04 after update?
This is that I have now:
This is that I want to get (black topbar and round corners):
I've tried all things (from this post):
sudo apt install gnome-session
sudo apt install ubuntu-gnome-default-settings
sudo apt install vanilla-gnome-default-settings vanilla-gnome-desktop
sudo apt install ubuntu-gnome-desktop
It gets default gtk-theme, gdm-theme, icons, but shell theme still from Ubuntu.
This also doesn't work.
