The xprop seems to indicate that the XKB config took a fallback path, pc105 instead of the applealu_iso you specified in Gnome. This issue looks different from that of comment #4.
Could you please elaborate on "I can't install xkeyboard-config"?
Also, concerning you keyswap issue, could you please install evtest:
sudo apt-get install evtest

sudo apt-get install evtest
start it: by-id/usb- Apple__ Inc_Apple_ Keyboard- event-kbd
sudo evtest /dev/input/
press the key labeled "@" on the keyboard(next to the 1 key), as well as the one labeled "<" (next to left shift), and paste the output here?
