Confirmed. p7zip-full or genisoimage is needed. The genisoimage recommends was dropped on Debian because p7zip-full was added as Depends. But in Ubuntu the depends was replaced by zip/unzip, which don't have the support for iso. Since genisoimage is already part of ubuntu-desktop, it's not a problem on a Ubuntu desktop. But it's a problem on other flavor that doesn't include genisoimage.
