In addition to the \OHPC{}
\iftoggle{isxCAT}{and \xCAT{} package repositories,}{package repository,}
the {\em master} host also requires access to the standard base OS distro
repositories in order to resolve necessary dependencies. For \baseOS{}, the
requirements are to have access to the BaseOS, Appstream, Extras, PowerTools,
and EPEL repositories for which mirrors are freely available online:

\begin{itemize*}
\item CentOS-8 - 8.4.2105
  (e.g. \href{http://mirror.centos.org/centos-8/8/}
             {\color{blue}{http://mirror.centos.org/centos-8/8/}} )
\item EPEL 8 (e.g. \href{http://download.fedoraproject.org/pub/epel/8/}
                        {\color{blue}{http://download.fedoraproject.org/pub/epel/8/}} )
\end{itemize*}

\noindent The public EPEL repository will be enabled automatically upon
installation of the \texttt{ohpc-release} package. Note that this does depend
on the CentOS Extras repository, which is shipped with CentOS and is typically
enabled by default.  In contrast, the CentOS PowerTools repository is typically
disabled in a standard install, but can be enabled as follows:

\begin{lstlisting}[language=bash,literate={-}{-}1,keywords={},upquote=true]
[sms](*\#*) dnf install dnf-plugins-core
[sms](*\#*) dnf config-manager --set-enabled powertools
\end{lstlisting}
