Papirus suite is specifically designed for KDE desktop but now the icon theme is available for other desktops as well which includes: Unity, Gnome, Mate, Cinnamon and others. Previously we had a ported version of Papirus KDE icons in the PPA but now it is directly supported and maintained by creator. There are two variants in this icon pack with light and dark panel icons, it has more than 1000 icons for different applications and still counting, if you find any missing icon then directly report it creator via Github page. There is an official PPA but it only offers packages for Ubuntu 16.04 and 14.04, so we added these icons in our PPA where it is available for all current Ubuntu versions and its derivatives. Arc theme suite used in the following screenshots and you can use Unity Tweak Tool, Gnome-tweak-tool to change themes/icons.

Terminal Commands:
sudo add-apt-repository ppa:noobslab/icons
