When prompting for installation of python3, PyGObject or GTK+ we print "(Y/n)?" and then only interpret 'ENTER', "y" or "Y" as a wish to proceed. If you answer with "Yes" or "yes", we will abort: > [root@lab-213 tl-4.13.0-server]# ./install-server > > Error: No Python 3.x interpreter found. > > A Python 3.x interpreter is required for ThinLinc. > I was trying to use the Python interpreter '/usr/bin/python3'. > > To install Python, please run this command: > > dnf install python3 > > Would you like to run this command now? > > (Y/n)? yes > > Please try again once Python is installed. This is very confusing.
