If you get an error like:

Setting up hp-snmp-agents (8.5.0.1.1-2) ...

insserv: Service snmp has to be enabled to start service hp-snmp-agents

insserv: exiting now!

update-rc.d: error: insserv rejected the script header

dpkg: error processing hp-snmp-agents (--configure):

subprocess installed post-installation script returned error exit status 1

Edit the file:

/var/lib/dpkg/info/hp-snmp-agents.postinst

and change the “update-rc.d …” to “update-rc.d -f …”

apt-get -f install and you should be back in business.
