I have observed something which could be the cause of the problem. On
older builds of CUPS I get the following prerm script for cups-daemon
(after build debian/cups-daemon/DEBIAN/prerm in source tree, after
install /var/lib/dpkg/info/cups-daemon.prerm):
----------
#!/bin/sh
set -e
# Automatically added by dh_installdeb
dpkg-maintscript-helper mv_conffile /etc/pam.d/cups-daemon /etc/pam.d/cups
1.7.3-2~ -- "$@"
# End automatically added section
# Automatically added by dh_installdeb
dpkg-maintscript-helper rm_conffile /etc/default/cups 1.7.1-6~ -- "$@"
# End automatically added section
# Automatically added by dh_installdeb
dpkg-maintscript-helper rm_conffile /etc/cups/cupsd.conf.default 1.7.1-3~ --
"$@"
# End automatically added section
# Automatically added by dh_systemd_start
if [ -d /run/systemd/system ]; then
deb-systemd-invoke stop cups.path >/dev/null
fi
# End automatically added section
# Automatically added by dh_installinit
if [ -x "/etc/init.d/cups" ] || [ -e "/etc/init/cups.conf" ]; then
invoke-rc.d cups stop || exit $?
fi
# End automatically added section
----------
The debhelpers added a call to explicitly shut down cups.path.
The same file in a Yakkety system or after building CUPS (2.2.1-2) in
Zesty is:
----------
#!/bin/sh
set -e
# Automatically added by dh_installdeb
dpkg-maintscript-helper mv_conffile /etc/pam.d/cups-daemon /etc/pam.d/cups
1.7.3-2~ -- "$@"
# End automatically added section
# Automatically added by dh_installdeb
dpkg-maintscript-helper rm_conffile /etc/default/cups 1.7.1-6~ -- "$@"
# End automatically added section
# Automatically added by dh_installdeb
dpkg-maintscript-helper rm_conffile /etc/cups/cupsd.conf.default 1.7.1-3~ --
"$@"
# End automatically added section
# Automatically added by dh_installinit
if [ -x "/etc/init.d/cups" ]; then
invoke-rc.d cups stop || exit $?
fi
# End automatically added section
----------
Here the call to stop cups.path is missing.
In both cases also the last part seems to be strange, as it seems to
support only System V Init and Upstart, not systemd. The "if" does not
check for the presence of systemd support (unit file).
