How to install Ubuntu Communitheme; Ubuntu Communitheme is the new Ubuntu theme build by the Community. This tutorial explains how to download themes for Ubuntu and how to install themes in Ubuntu. Users can easily install themes in Ubuntu Linux Systems.
Please Note: The team is currently still developing the theme, but you can try it out for yourself. Be warned though, this is a pre-release alpha state. These packages are mainly intended for the Communitheme designers to get a sense of what actually works in Ubuntu. Many icons are missing, some stuff is just a white squircle. You will find issues and stuff will break.
Please Note: These instructions install the entire Communitheme session; this includes the Gnome Shell, GTK and icon theme.
Install Ubuntu Communitheme
Run the following commands in Terminal to install Ubuntu Communitheme – new Ubuntu Theme;
sudo apt-get update
