password restrictions are different in the GUI and on the command line.

PS:

dummy   already is a tricky password for a German keyboard layout, since
the "y" on the German keyboard is a "z" :).

However, my local for Linux installs always is en and the keyboard
always de, but I don't experience an issue with my 16.04 install.

Just in case I wrote a keyboard.conf for my Ubuntu install ...

[rocketmouse at archlinux ~]$ cat /mnt/moonstudio/etc/X11/xorg.conf.d/keyboard.conf 
#Section "InputClass"
#       Identifier "keyboard"
#       MatchIsKeyboard "yes"
#       Option "XkbLayout" "de"
#       #Option "XkbVariant" "nodeadkeys"
#EndSection

... with all lines commented out ;).
