Cannot stat appimage

[Cyclic3]

I am trying to package CKAN as an AppImage. However, when I use pkg2appimage, I keep hitting two errors:

Which distribution and version are you running this on?

[Cyclic3]

I am using debian/sid. I tried doing this in a docker container, but kept hitting issues with running the program.

Just for fun, can you try the same on Ubuntu 14.04 (e.g., a Live ISO)? I'd like to know whether the host OS makes a difference or whether we have to search for the issue in either pkg2appimage itself or the yml recipe.
