[Pkg-virtualbox-devel] Bug#767651: virtualbox: no useful error message on outdated extension package

[Wilfried Klaebe]

Package: virtualbox
Version: 4.3.18-dfsg-1
Severity: important

Dear Maintainer,


   * What led up to the situation?

- upgrading virtualbox to current version without also upgrading extension package

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

ineffective:
- click "start" on a VM
- watch it beginning to boot
- see the VM's window vanish
- see the VM's state is now "Aborted"

effective:
- find "segfault", "error 4 in VBoxDD.so" in dmesg
- google
- find solution

   * What was the outcome of this action?

- VMs don't boot as expected

   * What outcome did you expect instead?

- an useful error message about needing to upgrade or remove the
outdated extension package
