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

  • It didn't work for me. Still using nautilus. – asdfkjasdfjk Aug 12 '17 at 18:17

I had the same error message in xfce4.

The error message says that this file is missing. So I had a look at which package provides this file and install it.

$ apt-file search exo-helper-1
libexo-1-0: /usr/lib/x86_64-linux-gnu/xfce4/exo-1/exo-helper-1
$ sudo apt-get install libexo-1-0

Now the message is gone.

However I am still encountering other errors in other places, so I guess either I can reinstall the whole desktop, or work through them one by one, or just ignore them.

I use apt-file above, which you can install:

sudo apt-get install apt-file
apt-file update
