This also affects me on Ubuntu 16.04 fresh install
I've set this in /etc/default/keyboard:
XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT="altgr-intl"
XKBOPTIONS=""
BACKSPACE="guess"
And the keyboard layout is most definitively not us/altgr-intl
I had this problem also on another laptop with Trusty Tahr 14.04 a few years ago and it caused me to move to Debian. Now i tried Ubuntu again, and the problem is still here (but not on debian).
