Yaru is the new Ubuntu theme that will be used as default in next Ubuntu releases.

Yaru, originally named “Communitheme“, is based on the GNOME Adwaita theme. The new theme contains GTK3 theme, Gnome shell theme, and icon theme. And Ubuntu 18.10 will ship with the new theme.

For Ubuntu 18.04 users who want to try the new Ubuntu theme, do:

• search for and install communitheme in Ubuntu Software.

  

• or launch terminal (Ctrl+Alt+T) and run command:

  snap install communitheme

  

Once installed, reboot and choose login with the ‘Communitheme’ session and enjoy.

In addition for those who don’t prefer Snap package, the new Ubuntu theme has a PPA repository.
