Unable to fully remove Juju

Question

After downloading Juju and playing around with it a little bit, my curiosity is satisfied. I decided to move on to other endeavors and uninstall Juju, although despite my best efforts a piece of Juju lives on in my syslog (on system boot):

kernel: [   16.509086] init: juju-jon-sample-file-storage main process (2163) terminated with status 1
kernel: [   16.509113] init: juju-jon-sample-file-storage main process ended, respawning
kernel: [   16.680103] init: juju-jon-sample-file-storage main process (2164) terminated with status 1
kernel: [   16.680138] init: juju-jon-sample-file-storage main process ended, respawning
kernel: [   16.873943] init: juju-jon-sample-file-storage main process (2165) terminated with status 1
kernel: [   16.873965] init: juju-jon-sample-file-storage respawning too fast, stopped

...actual number is much greater, but you get the idea, also present is the identical errors replaced with juju-jon-sample-machine-agent.

I tried

sudo apt-get remove juju
sudo apt-get purge juju
sudo apt-get autoremove

and

sudo update-rc.d juju remove
sudo update-rc.d juju-jon-sample-machine-agent remove
sudo update-rc.d juju-jon-sample-file-storage remove

Any ideas how to remove my that last piece of Juju stuck to my syslog? I am running 12.04 64 bit. Thanks in advance.

Solution 1

Juju installs some upstart files for local provider environments. Prior to removing juju it can be removed via juju destroy-environment for each local environment. Post removal that the upstart files can be removed from /etc/init by hand, their prefixed with the environment name and user name. update-rc.d doesn't work with upstart files afaik.

Solution 2

what you are missing is:

stop juju-jon-sample-file-storage

This will tell upstart to stop respawning the service. Then, you can safely delete the file /etc/init/juju-jon-sample-file-storage.

The other is not respawning, so should not be a problem in your logs or won't be seen dangling in your process list.

Hope this helps.
