Hey !
I use Ubuntu 17.04 on my server but i cannot install quickbox.
I just do the following cmd :
apt-get -y update; apt-get -y upgrade; apt-get -y install git lsb-release; \
git clone --recursive https://github.com/QuickBox/QuickBox /etc/QuickBox &&
bash /etc/QuickBox/setup/quickbox-setup
Could you try to support this version ?
Thanks
