I needed a arm ver of sentora on debian so this what come out
nano /etc/apt/sources.list
and delete all that is in there and replace it with this:
deb http://ftp.us.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.us.debian.org/debian/ jessie main contrib non-free
deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free
Get the installer
wget https://raw.githubusercontent.com/blynch555/debian-8-sentora-installer/master/sentora_install.sh
then run
chmod +x sentora_install.sh
then run the installer
sudo ./sentora_install.sh
