Issue:
The command unirun is used to install or upgrade an instance of Dollar Universe.
After starting the installation and choosing the option (i) for a new install, the script fails with the following error:
<install directory>/du_as_x.y.zz_linux_26_64/./tools/uniinstall: line xxx: host: not foundĀ 
Environment:
Unix, Linux
Cause:
The command "host" is not installed on the machine
Resolution:
Ask you system administrator to install the package that contains the system command "host"
On Redhat Linux this can be done by installing the packageĀ bind-utils-9.9.4-61.el7.x86_64 via yum
