error installing xfce4 -> udev_250-10_armhf.deb

i like to use vnc to connect to a virtual desktop.

Volumio 1.5 on Cubietruck.

Following steps were done:
rootfs expanded to 16GB
sudo apt-get update
sudo apt-get install xfce4

This cause an error during installation:
dpkg error processing … udev_250-10_armhf.deb

I tried to fix it with “install -f” option, without success.

Has anybody an idea to fix this error?

Best regards,
