I just upgraded my first preproduction system from Chef 10.12 to 10.14 and I’m now getting run fails due to chef-client trying to run usermod with bad syntax. Thanks to the nice error reporting in 10.14 I can give a human readable format of the error:
================================================================================
Error executing action create on resource ‘user[bob]’
Chef::Exceptions::Exec
usermod -u ‘5656’ bob -m returned 2, expected 0
Compiled Resource:
Declared in /var/cache/chef/cookbooks/some_cookbook/recipes/ubuntu.rb:124:in `from_file’
user(“bob”) do
recipe_name "ubuntu"
password "SURE…."
home "/home/bob"
username "bob"
supports {:manage_home=>true}
cookbook_name "some_cookbook"
retry_delay 2
uid "5656"
retries 0
action :create
shell "/bin/bash"
End
So what happens when you execute “usermod -u ‘5656’ bob –m” on a box:
sudo usermod -u ‘5656’ bob -m
Usage: usermod [options] LOGIN

-c, --comment COMMENT new value of the GECOS field

to INACTIVE
-g, --gid GROUP force use GROUP as new primary group
-G, --groups GROUPS new list of supplementary GROUPS

him/her from other groups
