[Pkg-nagios-devel] Bug#695226: pnp4nagios: Upgrade fails due to changed ownership

[Alma Mahler]

Package: pnp4nagios
Version: 0.6.16-2
Severity: normal
Tags: d-i

Dear Maintainer,

after apt-get upgrade npcd refused to start.

We use icinga and pnp4nagios:

ii icinga 1.7.1-4 amd64 host and network monitoring system - metapackage
ii icinga-cgi 1.7.1-4 amd64 host and network monitoring system - CGI scripts
ii icinga-common 1.7.1-4 all host and network monitoring system - support files
ii icinga-core 1.7.1-4 amd64 host and network monitoring system - core files

pnp4nagios packages see below; npcdmod.

User/Group: icinga:icinga

I already had problems, when I installed pnp4nagios 0.6.16-1. I had to change all ownerships on the relevant directories and files.

After the upgrade the npcd didn't start, no performance data was collected and written. The ownerships had been rewritten to nagios:nagios. I had to re-change all ownerships and start the icinga process manually. After that, everything worked fine. 

Would it be possible, to check user:group of the installation?

This is the history:

/var/log/syslog:

What we did to make it work:

chown -R icinga:icinga /var/spool/pnp4nagios/
chown -R icinga:icinga /var/log/pnp4nagios/*
chown icinga /var/log/pnp4nagios
chown -R icinga:icinga /var/lib/pnp4nagios/perfdata
chown icinga /var/lib/pnp4nagios/
/etc/init.d/npcd start
[ ok ] Starting Nagios Performance C Daemon (PNP4Nagios): npcd.
/etc/init.d/icinga start


After all that without any dpkg* or apt-*-command everything looks fine:

dpkg -l | /bin/grep pnp4nagios
ii pnp4nagios 0.6.16-2 all Nagios addon to create graphs from performance data
ii pnp4nagios-bin 0.6.16-2 amd64 Nagios addon to create graphs from performance data (binaries)
ii pnp4nagios-web 0.6.16-2 all Nagios addon to create graphs from performance data (web interface)
