I have just uploaded a first experimental appimage for Hugin 2016.2
The appimage has been tested on Fedora 24, and seems to work fine there, but I had no time yet for extensive tests.
If you like to give it a try and report eventual issues, here is the download link: https://pixls.us/files/Hugin-2016.2.0.be8da0221960.glibc2.14-x86_64.AppImage
One known issue is that the program complains for a missing hugin icon from time to time… I am still trying to fix that.
EDIT: the current recipe is available as a gist here.
