Issue
A customer copied files from /tmp/aveksa from one VM to another, instead of following the documented installation process. As a result, some files had incorrect file permission, owner and group values. Because these files did not have correct permissions, some Java packages could not be accessed by installation scripts located under /home/oracle/install

Resolution
The Fix:

As per our installation guide, it recommend not to copy any installation directories from machine to another, just create the needed directories then copy the installation packages:  

- Delete any exiting aveksa directory under /tmp

As root: 

# rm -rf /tmp/aveksa

- Create new aveksa directory under /tmp and create the packages and staging subdirectories. [RSA_IMG_v6.9_Installation_Guide page 31]

- Extract the packages under /tmp/aveksa/staging after copying them to packages.  [RSA_IMG_v6.9_Installation_Guide.pdf  page 31]

- Uninstall aveksa: 
As root:
 # cd /tmp/aveksa/staging/deploy
 # ./uninstall.sh

- Reboot the machine [ appliance or VM ]

- Start the installation script again.  [RSA_IMG_v6.9_Installation_Guide page 37]
