SysV-init:

s. Debian Bug report logs - #871543
broken init script (since 2017)

(bugs.debian.org/cgi-bin/bugreport.cgi?bug=871543)

bug: start-stop-daemon

command:
# /etc/init.d/saned stop

doesn't stop saned

solving problem according to Debian's bug report:

# sed -i -e 's/--retry --exec $DAEMON/--retry 10/g' /etc/init.d/saned

worked for me, after my dist-upgrade jessie -> ascii 2.1 stopped with

"Installing new version of config file /etc/init.d/saned ...
[....] Restarting SANE network scanner server: saned[....] Stopping
SANE network scanner server: sanedstart-stop-daemon: invalid schedule
