You can install Sentora with downloading the install.sh
CnetOS

Code:

Ubuntu

Code:

https://raw.githubusercontent.com/sentora/sentora-installers/master/install/Ubuntu-12_04/install.sh

Download the file install.sh or use wget, then chmod +x the file after downloading then hit ./install.sh

If you cannot download the file, copy the whole install script and create a file in your server called "install.sh"
then use the same method mentioned above "chmod +x" the file then hit ./install.sh in your terminal

That method works for me. This is just a temporary method of installing Sentora if you get broken link on install script.
