tasksel BeagleBoneBlack

I’m trying to install Gnome desktop on the BBB.
I have installed last immage in the SD(bone-debian-9.3-iot-armhf-2018-01-28-4gb.img) but when i try to install the gnome-desktop using tasksel i get this error:

tasksel apt-get failed (100)

In addction i have also expanded the file system.

Where i am wrong in what i am doing???

Thank in advance

How much space do you really have, Gnome Desktop will take a lot of space..
