[Pkg-cups-devel] Bug#319602: cupsys: Looks like a bashism in the postinst is causing this

[Michael Gurski]

Package: cupsys
Version: 1.1.23-14
Followup-For: Bug #319602


On one of the machines here, /bin/sh was linked to /bin/dash, and the
lastest sid upgrade of cupsys to 1.1.23-14 was failing with this exact
error.  This version commented out the Listen line it
/etc/cups/cupsd.conf, and added an include of
/etc/cups/cups.d/ports.conf.  With dash, ports.conf ended up
containing "-e -n Port 631".  Changing line 209 of cupsys.postinst to:

          /bin/echo -e -n "$VAL" > /etc/cups/cups.d/ports.conf

resolves the problem and creates ports.conf correctly.  Changing
/bin/sh to link to /bin/bash also fixes the problem, but I'm under the
impression that changing the postinst is the more correct method of
resolving this problem.  The tip-off to check ports.conf came from the
error messages in /var/log/cups/error_log:

E [17/Dec/2005:23:51:49 -0500] Unknown directive -e on line 1.
I [17/Dec/2005:23:51:49 -0500] Loaded configuration file "/etc/cups/cupsd.conf"
X [17/Dec/2005:23:51:49 -0500] No valid Listen or Port lines were found in the configuration file!

Specifically, the "Unknown directive" caused me to start comparing
md5sums between the broken system (i686) and a working system (amd64
and i686) with the same version, which led to the discovery of the
incorrect ports.conf file.
