Problem with dependencies

Question

I have a problem with dependencies on my Ubuntu 16.04 LTS. I'm trying to install folder-color by typing:

sudo apt-get install folder-color

And returns:

folder-color : Depends: python-nautilus but it is not going to be installed
                Depends: folder-color-common but it is not going to be installed
                Depends: python:any (< 2.8)
                Depends: python:any (>= 2.7~)
E: Unable to correct problems, you have held broken packages.

And I also tried to install or upgrade all packages but nothing. This also happens when I try to install gimp, please help me.
