dibbler-client's prerm script fails because it asks the init-script to stop the running dibbler client and the init-script forwards the request to the daemon, which fails (here re-run after a manual init-script start, to find out what went wrong): <quote src="/usr/sbin/dibbler-client stop"> | Dibbler - a portable DHCPv6, version 0.7.3 (CLIENT, Linux port) | Authors : Tomasz Mrugalski<thomson(at)klub.com.pl>,Marek Senderski<msend(at)o2.pl> | Licence : GNU GPL v2 only. Developed at Gdansk University of Technology. | Homepage: http://klub.com.pl/dhcpv6/ Attaching to process 1539 failed: No such process Warning: Can not guarantee for remote process termination Sending TERM signal to process 1539 Signal sending failed: No such process </quote> The init-script tells the daemon to stop in a sub-shell that follows up with true, apparently in an effort to ignore any failure here, but this doesn't seem to work ! The init-script fails, so prerm does too. I am thus unable to upgrade dibbler-client from 0.7.3-0.1. However, after a little perseverence, I found that commenting out the "set -e" line in /etc/init.d/dibbler-client sufficed to solve the problem; that's what causes the failing $DAEMON stop to abort the script. That implies the following suggestion for how to fix this: change <prior> stop) echo -n "Stopping $DESC: " ($DAEMON stop 2>&1 > /dev/null; true) echo "$NAME." ;; </prior> to <fixed> stop) echo -n "Stopping $DESC: " ($DAEMON stop 2>&1 > /dev/null || true) echo "$NAME." ;; </fixed> and you should be OK :-) The issue is that set -e is inherited by the sub-shell, which duly exits (failing) before your ; true can have any effect; however, || true does what you want - set -e only applies to the end result of any chain of || and && operations. You need to do the same in restart|force-reload) as well, where it calls stop. I also note that your 2>&1 > /dev/null says "send errors to where standard output would previously have gone, but send standard output to /dev/null"; if what you want is "send errors and output to /dev/null" then you need to do the redirects (somewhat counter-intuitively [*]) in the reverse order: >/dev/null 2>&1 That applies to both stop and start uses of $DAEMON. [*] if you doubt this, try the following: (echo stderr >&2; echo stdout) 2>&1 >/dev/null and vary the outer redirects to see how they interact. In the form given, using your redirect, stderr gets displayed. In the reversed >/dev/null 2>&1 form, all output is sent to /dev/null -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (500, 'testing'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.32-trunk-686 (SMP w/2 CPU cores) Locale: LANG=en_GB.ISO-8859-15, LC_CTYPE=en_GB.ISO-8859-15 (charmap=ISO-8859-15) Shell: /bin/sh linked to /bin/bash Versions of packages dibbler-client depends on: ii debconf 1.5.32 Debian configuration management sy ii libc6 2.11.2-2 Embedded GNU C Library: Shared lib ii libgcc1 1:4.4.4-5 GCC support library ii libstdc++6 4.4.4-5 The GNU Standard C++ Library v3 ii ucf 3.0025 Update Configuration File: preserv Versions of packages dibbler-client recommends: ii dibbler-doc 0.7.3-1 documentation for Dibbler dibbler-client suggests no packages. -- debconf information: * dibbler-client/start: true dibbler-client/title: * dibbler-client/options: dns, domain * dibbler-client/interfaces: eth0 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
