unable to upgrade to 10.5

unable to upgrade to 10.5

I recently upgraded to 10.0 without issues. I took another backup but when I try to upgrade to 10.5 it always reverts. I am not using Postgresql  but in the log I keep seeing
Upgrading PostgreSQL  Completed extracting                    15% Completed     [|]   [-]
Error occured while migrating postgres database.
My database is MSSQL. is there a way to get it to ignore Postgresql. I have been using ManageEngine_ServiceDesk_Plus_10_0_0_SP-1_0_0_Linux.ppm when attempting to do the upgrade

OS: Ubuntu 16
DB Type MSSQL
