Upgrading to 10500 fails

Upgrading to 10500 fails

Hello everyone,

like in the topic from @ ayakobchuk in  https://pitstop.manageengine.com/portal/community/topic/update-to-10500-failed I have a problem of upgrading to 10500 too with the same Error:

Upgrading PostgreSQL  Completed extracting                    15% Completed     [|]   [-]
Error occured while migrating postgres database.
                                          100% Completed     [-]   98% Completed     [/]ed     [|]
Uninstallation Completed

The only difference: We're running on Debian 9

It's really strange ... Where can I get more logs or assistence?
