So I am attempting to upgrade puppet. Part of the upgrade process calls out to disable all agents, using mco with puppetd. Everything I google, (since the puppet docs only explain how to do this in the PE version) state, I should have a command under mco for puppetd. Any ideas why its missing?:

root@puppet:~$ mco
The Marionette Collective version 2.5.2

usage: /usr/bin/mco command <options>

Known commands:

   completion           facts                find
   help                 inventory            ping
   plugin               rpc

Type '/usr/bin/mco help' for a detailed list of commands and '/usr/bin/mco help command'
to get detailed help for a command

Try the following to see the help. Remember if you didn't install the mcollective puppet agent, not just the mcollective agent, on the servers and the mcollective puppet client on your local machine mco won't be able to run (or see) the puppet plugin. Or the service pluging. Or the nrpe plugin. Or the package plugin.

mco help puppet

and list of mcollective plugsin I have installed

~ $ dpkg --list | grep mcollective
ii  mcollective                      2.5.2-1puppetlabs1 
ii  mcollective-common               2.5.2-1puppetlabs1
ii  mcollective-filemgr-agent        1.0.1-1
ii  mcollective-filemgr-common       1.0.1-1

ii  mcollective-iptables-common      3.0.1-1
ii  mcollective-nrpe-agent           3.0.2-1 
ii  mcollective-nrpe-common          3.0.2-1
ii  mcollective-package-agent        4.3.0-1puppetlabs1
ii  mcollective-package-common       4.3.0-1puppetlabs1
ii  mcollective-puppet-agent         1.7.2-1puppetlabs1 
ii  mcollective-puppet-common        1.7.2-1puppetlabs1 
ii  mcollective-service-agent        3.1.2-1 
ii  mcollective-service-common       3.1.2-1

When you install a plugin you will need the -client package on the machine from which you run your mco command line statements. The agent packages need to be on all the other machines.

I prefer to stop the service completely for an upgrade. mco puppet disable will leave the daemon running which makes the upgrade more likely to fail. Here are the command I use. Stop, upgrade using batch sizes so all the the agent aren't started at once, and then check status.

mco service puppet stop -S "environment=stage" # or whatever filter
mco package puppet upgrade --batch 2 --batch-sleep 30 -S "environment=stage" 
mco puppet status -S "environment=stage"

mco service is also not a known command.

"Remember if you didn't install the agent on the servers and the client on your local machine mco won't be able to run (or see) the puppet plugin." covers your problem.

mco is installed on the master and all agents.

Alright I'll admit the plugin was unclear since there is the agent and then the plugin agents, mcollective-puppet-client mcollective-puppet-common mcollective-puppet-agent

ah, ok. So it is just likely that I am missing the puppet plugin for MCO, on the server side?

While this does provide some intuitive information when I get to the upgrade, it does not address the question at hand. mco help <x> works, but puppetd and puppet are not showing as command so it fails. Is it neccessary to disable the puppet agents, by using mco and puppetd, as called out here:
