Description Alex Schultz 2017-04-07 15:13:52 UTC 
Cloned for OSP10

+++ This bug was initially created as a clone of Bug #1439952 +++

Description of problem:
openstack minor update - list_updates=$(yum list updates) never returns empty string

/usr/share/openstack-tripleo-heat-templates/extraconfig/tasks/yum_update.sh
~~~
(...)
list_updates=$(yum list updates)

if [[ "$list_updates" == "" ]]; then
    echo "No packages require updating"
    exit 0
fi
(...)
~~~

The if condition never fulfills!

This can be easily tested:
~~~
[root@undercloud-4 ~]# list_updates=$(yum list updates)
[root@undercloud-4 ~]# echo $list_updates
Loaded plugins: search-disabled-repos
~~~

Expected results:
This should be `yum -q list updates`, and the if condition will be reached
