At some point in time you were running SGOS 6.6, but you have since downgraded to 18.104.22.168, you will received the following error message when installing policy:
Error: Variable Linker Error: variable not defined: 'variable.bc_notify1=variable.bc_notify2'
The primary reason for this is that the current policy created from newer versions of SGOS includes features not supported within previous versions.
To resolve this issue, use SSH to connect to the proxy CLI and issue the following commands::
