and if i do
sudo /usr/local/sbin/install_desktop.sh     
the answer is :       Usage: /usr/local/sbin/install_desktop.sh <mate|i3|gnome|xfce4|lxde>

and then i wrote
sudo /usr/local/sbin/install_desktop.sh lxde
and the answer
Unpacking libmali-rk-utgard-450-r7p0:arm64 (1.6-1ayufan7) ...
dpkg: error processing archive /var/cache/apt/archives/libmali-rk-utgard-450-r7p0_1.6-1ayufan7_arm64.deb (--unpack):
