Error executing action `create` on resource 'ruby_block[omnibus chef killer]'


Hello guys,

I am trying to run omnibus_updater to update chef-clients on nodes, but at every node on which i’m running omnibus_updater on, I’m getting the following error:

================================================================================ Error executing action ``create on resource 'ruby_block[omnibus chef killer]’

New omnibus chef version installed. Killing Chef run!

It’s a CentOS 6.6 machine, the cookbook version is 1.1.1 and i’m trying to update chef-client from 12.7.2 to latest 12.12.15

Thank you,


The only solution I got so far is to run chef-client again on the affected nodes. That seems to solve the problem and after the run, chef-client is updated.

Is there another solution?
Thank you.


This is the intended behavior as the cookbook is written currently. The cookbook needs to stop Chef Client after the upgrade to ensure that cached data such as the location of ohai plugins on disk is refreshed.

Currently the only way for a recipe to make chef exit that works for all cases is to raise a fatal error; the reboot resource has some functionality to end a Chef Client run early without a fatal error, but it won’t force Chef Client to exit in all cases, so the cookbook uses a fatal error instead.


thank you.
