How to upgrade frappe 14 to 15?

can anyone help solve this problem? I never specifically installed frappe-14, but why does it say frappe-14 here? Because of this I can’t install ERPNext-15. How to update frappe-14 to frappe-15? or how to uninstall frappe-14 and then install frappe-15?

please help me, I didn’t find any information to update frappe or uninstall frappe-14.
