It’s mentioned here: Whonix Forum
You can install manually by following the advice here: Whonix Forum
[quote=“nrgaway, post:5, topic:1017”]Maybe try to download it directly?
http://sourceforge.net/projects/qubesos/files/rpm/r2/templates-community/
Then you will need to copy it to dom0 and use yum to install it. Assuming you download the file in a VM named ‘web’ and the downloaded file is located in the users ‘Downloads’ directory, you can copy to dom0 as follows:
[code]
In dom0 terminal session
cd /tmp
qvm-run --pass-io web ‘cat Downloads/qubes-template-whonix-workstation-gnome-2.1.8-201503092029.noarch.rpm’ > qubes-template-whonix-workstation-gnome-2.1.8-201503092029.noarch.rpm
yum install ./qubes-template-whonix-workstation-gnome-2.1.8-201503092029.noarch.rpm

Hope this helps. Have a nice day!
