Changing the build dependency to the -dev package (from libzbar0 to libzbar-dev) has fixed the failing reprotest-kernel job. I tried this out after reading that ctypes.util.find_library is usually used to lookup build-time dependencies rather than run-time dependencies. Local builds and other reprotest variations work fine without the -dev package. Can someone share some insight into why reprotest-kernel needs the -dev package?
