Troubleshooting tips :

If ‘install.sh’ is failing with the error ‘/bin/bash^M : bad interpreter error’ due to an windows character in the file, Please run the following command first and run ‘install.sh’ again.

open your file with vi then set unix with:

:set ff=unix

:wq!

OR

# sed -i -e ‘s/\r$//’ install.sh

# ./install.sh
