We have made you repositories to easily install up-to-date releases of various Numix artworks.
If you use Ubuntu, add our Ubuntu PPA to get Numix packages. Fire up a Terminal and run the following:
sudo add-apt-repository ppa:numix/ppa
For Fedora, Red Hat and OpenSUSE, we have setup repos on OpenSUSE build service.
Alternatively, if you are on Fedora, install Fedy and run the following command in the Terminal:
sudo fedy -e numix_themes
