PiTFT Plus 480x320 3.5" TFT+Touchscreen - Not working

I purchased recently this Adafruit PiTFT 3.5" Touch Screen for Raspberry Pi.
I just following the easy-install instructions by lady ada.
First I installed the latest version of Raspbian on my SD card.
Since the thing was not working I tried with, following the indications, the version of Rasbian of 13 March 2018. Considered more suitable.
The whole thing is loaded from terminal but at the end there is this warning:
[PITFT] Checking init system…
Found systemd
/boot is mounted

[PITFT] Installing Python libraries & Software…
Installing Pre-requisite Software…This may take a few minutes!
E: dpkg è stato interrotto. È necessario eseguire “sudo dpkg --configure -a” per correggere il problema.
WARNING : Apt failed to install software!
Can you give me a hand?
Thank you in advance.
