Yes I did but I created a propellor property in order o maintain my sbuild chroot. Indeed this is a detail. So I end up with a tar.gz owned by root:root Then comes the upgrade whcih changed the owner into sbuild:sbuild. Why sbuild which is run as root do not want to lock something which is not owned by the root ? I do not understand this point. > sudo chown root:root /var/lib/sbuild/unstable-amd64.tar.gz thanks, I already done it :) Cheers Fred
