[ubuntu] After upgrade to 16.04, missing Documents / Files (Unable to find the requested file)

Hi all,
I wanted to upgrade from 14.04 to 16.04, but I messed it up badly (explained here: https://ubuntuforums.org/showthread.php?t=2331176)
so that I decide to re-install from scratch with Live CD.

First, I tried the option of re-installing only the operating system, but it failed. So, then, I chose the option of erasing everything, but then from the partition I didn't format /Home.

The laptop works quite well. I had some little problems, like WIFI not working, but I solved unabling Secure boot (https://ubuntuforums.org/showthread.php?t=2331302).

Now, the last problem I seem to face is that, somehow, my old and new account/use conflict. Said differently, there is some problem with /Home.

My previous /Home is there with all files (screenshoot attached). I anyway keep all my important files on Dropbox (which works correctly), and I could delete without problems any other folders. I caot opens the ones below Computer, and before Server (See attached picture)

For example, once I click on Documents or Music or Videos,
I get the following error message (screenshoot attached):
"Unable to find the requested file. Please check the spelling and try again.
Unhandled error message: Error when getting information for file '/home/jhoy/Documents': No such file or directory"

I get also another problem with Backup, that I had set automatically since Ubuntu 14.04. How I get this error message:
Backup: "Failed to execute child process "duplicity" (No such file or directory)"

This is my partition, I've not changed it manually
