  Parallel depmod failure with dkms autoinstall

  Description of problem
  --

  "dkms autoinstall" installs DKMS modules in parallel, potentially executing
  several depmod instances in parallel.

  The resulting race condition causes depmod to fail and dkms install as
  well.

  This problem is critical because some DKMS modules can be left in "built"
  state after a kernel upgrade, thus the kernel modules will not be re-installed
  in /lib/modules/.

[Kernel-packages] [Bug 1608499] Re: Parallel depmod failure with dkms autoinstall

[Julien Floret]

Hello,

I have tested 2.2.0.3-2ubuntu11.2 from xenial-proposed and
2.2.0.3-1.1ubuntu5.14.04.8 from trusty-proposed.

Both packages fix the problem.

Thanks!

  Description of problem
  --

  "dkms autoinstall" installs DKMS modules in parallel, potentially executing
  several depmod instances in parallel.

  The resulting race condition causes depmod to fail and dkms install as
  well.

  This problem is critical because some DKMS modules can be left in "built"
  state after a kernel upgrade, thus the kernel modules will not be re-installed
  in /lib/modules/.

[Kernel-packages] [Bug 1608499] Re: Parallel depmod failure with dkms autoinstall

[Timo Aaltonen]

Hello Julien, or anyone else affected,

Accepted dkms into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/dkms/2.2.0.3-2ubuntu11.2 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!

  Description of problem
  --

  "dkms autoinstall" installs DKMS modules in parallel, potentially executing
  several depmod instances in parallel.

  The resulting race condition causes depmod to fail and dkms install as
  well.

  This problem is critical because some DKMS modules can be left in "built"
  state after a kernel upgrade, thus the kernel modules will not be re-installed
  in /lib/modules/.

  Parallel depmod failure with dkms autoinstall

Status in dkms package in Ubuntu:
  Confirmed

Bug description:
  Description of problem
  --

  "dkms autoinstall" installs DKMS modules in parallel, potentially executing
  several depmod instances in parallel.

  The resulting race condition causes depmod to fail and dkms install as
  well.

  This problem is critical because some DKMS modules can be left in "built"
  state after a kernel upgrade, thus the kernel modules will not be re-installed
  in /lib/modules/.

Title:
  Parallel depmod failure with dkms autoinstall

Status in dkms package in Ubuntu:
  Confirmed

Bug description:
  Description of problem
  --

  "dkms autoinstall" installs DKMS modules in parallel, potentially executing
  several depmod instances in parallel.

  The resulting race condition causes depmod to fail and dkms install as
  well.

  This problem is critical because some DKMS modules can be left in "built"
  state after a kernel upgrade, thus the kernel modules will not be re-installed
  in /lib/modules/.

  "dkms add", then run "dkms autoinstall".
