Netflow Analyzer update from 6 to 7

Hi I noticed that this has been posted before, but it was in march this year without any real solution. Thus the repost.

I am trying to update our Adventnet Netflow Analyzer from 6.0 to 7.0. Going through the steps outlined in Service Packs guide, the output I got was :

/etc/netflow/NetFlow/bin$ sudo ./UpdateManager . sh
backup has been done
.: 44: setcommonenv . sh: not found

From the last post regarding the same error, an output of ".setcommonenv . sh" was requested. I executed the same file but it just completes without any msgs.

/etc/netflow/NetFlow/bin$ sudo ./setcommonenv . sh
/etc/netflow/NetFlow/bin$

OS - Ubuntu 7.10 gutsy Gibbon Linux 2.6.22-14-server

Any help would be appreciated. thank you
