Can not import <DFMiniMp3.h> library on linux Arduino IDE.

I have tried many files, sites or forums diférents but I have never managed to import this library and without it I can not realize my project.
I do not know what to do so I just ask for help on this forum. :frowning:

If the library is created properly, importing the library into the IDE on Linux is the same as on Windows.

I use Linux Mint 18.
