Module 2 has an issue that it might not execute on most Ubuntu installations. It seems to be something we can’t do anything about. Ubuntu simply mounts physical UDF discs as non-executable for some reason. Windows and OS X mounts as executable by default.
A workaround that doesn’t require copying files is to, in a terminal:
umount /media/Greenlandic\ 2…after which launching the program from the LG2 folder on the desktop will work.
sudo mount -omode=0777 -t udf /dev/sr0 LG2
Or if you have downloaded the ISO file and it doesn’t mount correctly either, replace the last step with:
sudo mount -o loop -omode=0777 -t udf LearnGreenlandic2.iso LG2
