do_fetch[file-checksums], expression was
${@bb.fetch.get_checksum_file_list(d)} which triggered exception
MalformedUrl: The URL: 'pippo-fs' is invalid and cannot be interpreted

Even more interesting this simple recipe

inherit dpkg-base
SRC_URI = "apt://${PN}"

download the package ONLY if the package is into the debian repository but
NOT if the package is in a external repository defined into conf/ but
available with IMAGE_PREINSTALL

I have also tried to change the repository but it did not work either
