Bug Description

[Impact]

Currently the DKMS package fails to install on supported custom
kernels that are based on 4.15. That includes the current 4.15
hwe-edge and some of the custom and cloud kernels as well.

[Test Case]

Install the v4l2loopback-dkms package with the 4.15 hwe-edge kernel. The
package installation should proceed without any errors.

[Regression Potential]

Although new patches were added, the regression risk is very low since
the new changes are conditionally compiled based on the kernel
version.

Besides that, the new package was tested with the following kernels in
an amd64 environment:

- linux-generic 4.4
- linux-hwe 4.13
- linux-hwe-edge 4.15
- linux-azure 4.15

This debdiff looked mostly good. The version string wasn't quite typical of what we use for updates to stable releases. I'd prefer that you follow these guidelines when updating a package that hasn't already been through an SRU (you'll mostly likely have to follow the versioning scheme of the previous uploader if it has already been through at least one SRU):

I've adjusted the version to be 0.9.1-4ubuntu0.1 and sponsored the upload to xenial-proposed. Thanks!

Hello Marcelo, or anyone else affected,

Accepted v4l2loopback into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/v4l2loopback/0.9.1-4ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
