Backport autopkgtest script to precise/trusty

[Martin Pitt]

The kernel team has requested that we run DKMS tests via autopkgtests for precise and trusty the same way that we now do for vivid and upwards. For this we need to backport debian/scripts/dkms-autopkgtest from https://launchpad.net/ubuntu/+source/dkms/2.2.0.3-2ubuntu1.

TEST CASE:
 Run autopkgtest for a DKMS package:

   adt-run bcmwl --- qemu adt-trusty-amd64-cloud.img # or use a precise image, or "--- lxc <container-name>"

This currently fails with

   adt-run [15:18:24]: test command1: /usr/lib/dkms/dkms-autopkgtest
   adt-run [15:18:24]: test command1: [-----------------------
   bash: /usr/lib/dkms/dkms-autopkgtest: No such file or directory

With the proposed packages this should work and look more like

Setting up bcmwl-kernel-source (6.30.223.248+bdcom-0ubuntu4) ...
Loading new bcmwl-6.30.223.248+bdcom DKMS files...

adt-run [17:23:43]: test command1: -----------------------]

REGRESSION POTENTIAL: Almost zero. dkms is an arch: all package, thus no miscompilation possible. The new script is not being used in dkms' actual operation, only when being invoked through autopkgtest. As every DKMS package test fails right now, there is no test regression possible either.

I uploaded the precise and trusty backports. They were straightforward, dkms hardly changed since precise. I tested them locally with installing the built deb into a precise/trusty container, and ran "adt-run bcmwl --- lxc precise-dkms-backport".

Hello Martin, or anyone else affected,

Accepted dkms into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/dkms/2.2.0.3-1.1ubuntu5.14.04.2 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 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 to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

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

I now also successfully ran the test case above on my local laptop.

The verification of the Stable Release Update for dkms has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
