openvswitch-datapath-dkms neads linux-headers

[David Medberry]

To successfully "apt-get install openvswitch-datapath-dkms" there needs to be a dependency or recommends for linux-headers. When installing this in an oneiric virtual machine, the kernel modules don't build without this. I see a recommends for linux-headers in dkms but I'm not sure that gets pulled in when running the "apt-get install openvswitch-datapath-dkms" the first time.

Ubuntu 11.10
Source: openvswitch
Version: 1.2.0-1ubuntu3

And all of this looks similar in Precise.

Hi Dave

Looking at the dependencies of this package - specifically dkms:

Recommends: fakeroot, menu | sudo, linux-headers-686-pae | linux-headers-amd64 | linux-headers-generic | linux-headers, linux-image

I think that this is not a direct dependency because you have to ensure that the correct headers are installed for the type of kernel you are using.

What type of kernel is your VM using?

I was reminded of the bug when I hit it again myself.

I'm not sure there is much we can do - but I'm going to push it through to triaged

Packaged depending on headers will universally always be wrong, as they can't divine which kernel you have installed. The correct thing to do is to have the 'linux-$flavour' package installed matching your kernel flavour, which will make sure your headers are always in sync. All our sane installers do this for you from the get-go.
