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 
Unix, Linux
The command "host" is not installed on the machine
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
