Ubuntu – Syntax error near unexpected token `newline’ while installing Predictionio

bashcommand linescripts

I'm new to Prediction.io and when I try to install it following the instruction at this page I get the following error:

bash: -c: line 0: syntax error near unexpected token `newline' 
bash: -c: line 0: `<!DOCTYPE html>'

The command I'm executing is 

bash -c "$(curl -s https://install.prediction.io/install.sh)"

How can I solve this? What went wrong?

Well, the file that you're putting between the quotes, to execute as a bash command, is a 15917 byte bash script (written by Somebody Else, and you're running it without inspection, but that's off topic). If you split it up into simpler commands, you could: 

curl -s https://install.prediction.io/install.sh >install.sh
# inspect install.sh here
bash ./install.sh
# if it fails, do bash -x ./install.sh
rm ./install.sh
