Package: zutils Version: 1.7-7 Severity: serious zutils fails to upgrade from 1.7-6 to 1.7-7 as follows for me:
Preparing to unpack .../60-zutils_1.7-7_amd64.deb ... preinst called with unknown argument `upgrade' dpkg: error processing archive /tmp/apt-dpkg-install-9FRsIU/60-zutils_1.7-7_amd64.deb (--unpack): new zutils package pre-installation script subprocess returned error exit status 1 Errors were encountered while processing: /tmp/apt-dpkg-install-9FRsIU/60-zutils_1.7-7_amd64.deb I suspect that this is caused by this change in 1.7-7: * Dropping temporary upgrade handling from 1.7-2, not needed anymore. Probably too much has been removed from preinst. -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (990, 'unstable'), (980, 'unstable-debug'), (600, 'testing'), (111, 'buildd-unstable'), (111, 'buildd-experimental'), (110, 'experimental'), (105, 'experimental-debug') Architecture: amd64 (x86_64) Kernel: Linux 4.18.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE=C.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages zutils depends on: ii libc6 2.28-3 ii libgcc1 1:8.2.0-13 ii libstdc++6 8.2.0-13 Versions of packages zutils recommends: ii bzip2 1.0.6-9 ii lzip 1.20-4 ii xz-utils 5.2.2-1.3 zutils suggests no packages. -- no debconf information
