Qreator in 16.04 and beyond requires the fix to python-qrencode and this fix [1] to Qreator itself. See bug 1573577 for more details.
The 16.04 Qreator package with the fix is available in the Qreator PPA. You can install it as a workaround as per the instructions on that bug. Adding them here again: sudo add-apt-repository ppa:qreator-hackers/qreator-stable sudo apt update sudo apt install qreator python-qrencode And again, if someone wants to lend a hand in doing an SRU upload to backport the Qreator fix to 16.04, help would be very welcome!
