Hi Michael and everybody, just for the record, I just stumbled on that bug on a virtual machine that I administrate and ran the postinst script with "set -x": Setting up udev (215-17+deb8u4) ... + case "$1" in + update_hwdb + udevadm hwdb --update --usr + addgroup --system input addgroup: The group `input' already exists and is not a system group. Exiting. dpkg: error processing package udev (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: udev E: Sub-process /usr/bin/dpkg returned an error code (1) It seems that the error is really caused by adduser... I then circumvented the problme by deleting the "input" group and running apt-get again, as suggested earlier in this thread. Interesingly, I had a similar error with a systemd package and the systemd-journal user. Since the machine where I saw the problem has been installed by somebody else than me, I can not exclude that the groups were added by hand, however I would find this surprising.
