My current investigation shows that the isohybrid command indeed is part of the syslinux-utils package.

• On Ubuntu 16.04.1 (64-bit, not tested on 32-bit) the -u option gives error. This needs further investigation.
• Using just isohybrid (without options) works fine. As result, the final ISO image size grows.

Considering the above, I believe the better option is to remove the isohybrid functionality at all. MLL is educational tool and running MLL from USB flash drive can be achieved with simple syslinux installation either manually or by using the installer script which is still under development.

I have removed the isohybrid support from MLL.
