I am trying to install dolphin file manager in my ubuntu 17. So I was following this answer. But when I run this exo-preferred-applications
in terminal I get this message
/usr/bin/exo-preferred-applications: 11: exec: /usr/lib/x86_64-linux-gnu/xfce4/exo-1/exo-helper-1: not found
I want to set dolphin as my default file manager. So how can I do this? I am using ubuntu 17 and unity 7.5
