Generating Packages with (apt-ftparchive.conf is attached below.):
apt-ftparchive generate --contents=off ./apt-ftparchive.conf
Generated Packages contains:

However, on disk, we have very different file size & checksums:
ll nemo*
-rw-r--r-- 1 actionmystique actionmystique 1082324 Feb 27 15:01 nemo_2.8.6-11_amd64.deb

md5sum nemo_2.8.6-11_amd64.deb
68d5c945d9ccd9d3d2807ba46e33cc42 nemo_2.8.6-11_amd64.deb

If we generate Packages differently with:
apt-ftparchive packages . > Packages
Generated Packages contains this time correct file size & checksums:

What is very strange is that all other packages are correctly described by Packages when using the first method for generating Packages.

I have also uploaded the deb.
Any suggestion?
