## Description

Hello,

I’m trying to upgrade my packaged installation of openproject-core from 4.2 to 5.0.5-1449140564.d088c7a.jessie  
My system:

  - OS: Debian Jessie
  - DB: Postgres
  - OpenProject Core

When I run `sudo openproject configure` after the package installation/upgrade I get the following fatal error:

    [openproject] ./bin/postinstall
    rake aborted!

What could be the reason?
