post-install script fails

[Arie Skliarouk]

On quantal, xymon-client 4.3.7-1 has mistake in /var/lib/dpkg/info/xymon-client.postinst:
pkill -u hobbit vmstat

This fails if there is no hobbit or vmstat running, and then the post-install script exits with error.

dpkg: error processing xymon-client (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 xymon-client

Already fixed in the package's git repository.

You don't need to. It's a missing Pre-Depends on procps. Just install
procps and run "dpkg --configure --pending" afterwards (as root).

The according git commit is:

Because of an other bug I tried this update from 4.3.0 on an precise/12.04 system to 4.3.7 (quantal package) and I encountered an postinstall error, too. The installation script won't move the "rep" and the "snap" directories to the new "xymon" locations. I had to delete them. I'm not sure if this info helps here ...

Installing procps does not help. 'pkill -u hobbit vmstat' still fails because there is no process to kill.

The fix would be to change the line to 'pkill -u hobbit vmstat || true'.

This bug was fixed in the package xymon - 4.3.17-2

---------------
xymon (4.3.17-2) unstable; urgency=low

  * Upload to unstable again.

  [ Christoph Berg ]
  * Always write /var/run/xymon/xymonclient-include.cfg on clients

  [ Axel Beckert ]
  * Add build-dependency on libc-ares-dev to avoid using embedded code
    copy at xymonnet/c-ares-1.7.3.tar.gz
  * Fix includes for graph definitions (xymongraph.d → graphs.d)
    + Add a Breaks for hobbit-plugins << 20140519~
  * Remove reference to /etc/apache2/ from xymon-client.NEWS
  * Fix remaining issues of the Apache 2.2 → 2.4 transition
    (modifies mostly debian/rules, xymon.postinst and xymon.maintscript)
    + Fix conffile paths in README.Debian and xymon.maintscript
    + Use dh_apache2 and apache2-maintscript-helper
    + Add build-dependency on dh-apache2.
    + Add lintian override for missing-build-dependency-for-dh_-command
      (see #748688)

  * Let xymon depend on perl until after the Jessie release to make sure
    prename is there for the data migration from hobbit to xymon.
  * Add lintian override for apache2-reverse-dependency-calls-invoke-rc.d
    -- it finds the fallback for apache2-maintscript-helper unavailability
