I am not familiar with ubuntu at all

I have developed the reports in PRD Previewed and published to several systems including windows and Ubuntu works fine but in
Ubuntu when tried to view in PUC i get to see only a blank page no error nothing no error in console as well.

Preview works fine in Ubuntu also with PRD

Server 5.0.1 ce
Prd: 5.0.1 Stable

I am not able to get .pentaho file as in windows c drive to see the logs of prd
