Problem with virtualbox plugin install in 3.0 OMV

Good morning,

I have installed OMV 3.0.99 (erasmus) from scratch on my HP microserver gen8. KERNEL Debian GNU / Linux, with Linux 4.9.0-0.bpo.6-amd64
I have had version 2.0, where everything worked correctly but I wanted to update my system.

I run into the following problem when trying to install the virualbox plugin:

(Image Attached)

-I have tried to install the packages, etc.
-I have surfed the forums I have been testing by touching the sourcelist, changing the kernel, etc.
-I have been trying several things that I have read in the forums.
-I tried to install the Backports-Kernel but in version 3.0 I do not see the tab in omv-extras> kernel.

I need help, since I would like to be able to move to version 3.0 but if virtualbox does not work ...

Thank you very much.

Greetings.

It's give me an error:

Reading list of packages ... Done

E: The linux-header-amd64 package could not be located

Thanks

I had the same problem. In the command line the s letter is missing.
apt-get install -t jessie-backports linux-headers-amd64

That's run!! Thanks!!
