NagiosXi Offline not working

[andromeda]

Hello,

I have an isolated environment with no Internet access so I needed an offline upgrade procedure and used what Nagios posted:
Offline Upgrade Instructions
Upgrade to the latest version by downloading the latest offline tarball.
mkdir -p /tmp/rpms
cd /tmp/rpms
rm -rf nagiosxi*
Place the tarball downloaded from above in /tmp/rpms/
tar xzf nagiosxi*
cd nagiosxi*
./upgrade


[root@nagiosxi nagiosxi]# ./upgrade
package nagiosxi-shellinabox is not installed

---------------------------------------
However it failed saying it could not contact nagios mirror sites?? Why is this method called offline then?

Please help.
Thanks.
