Hello, I tried to install wok-2.0.0-0.noarch.deb on Ubuntu 14.04.3 LTS but dpkg fails because of the exit error 127 in the postinst script. It seems that "type /bin/systemctl" exits with this error, because this file is missing (Ubuntu 14.04 is not using systemd). I changed the script like this: #systemd_exists=$(type /bin/systemctl > /dev/null 2>&1; echo $?) #if test $systemd_exists = "0"; then if [ -e /bin/systemctl ]; then /bin/systemctl enable wokd > /dev/null 2>&1 /bin/systemctl daemon-reload > /dev/null 2>&1 /bin/systemctl start wokd > /dev/null 2>&1 fi ... and it worked for me. Kind regards, Alex
