Bug Description

kdump-tools is not installable on arm64 because it depends on makedumpfile, which is not currently built on arm64. Adding arm64 to the Architecture list in debian/control is all that is needed for it to build successfully.

That said, xenial's version was too old to support filtering kdump-enabled xenial kernels (>= 4.10.0). So, this doesn't actually produce a *useful* makedumpfile, but does allow kdump-tools to be installed, which unblocks collection of (unfiltered) crash dump files.

[Test Case]
On an arm64 system:
 sudo apt install kdump-tools

[Regression Risk]
The only change here is to make a binary package available on arm64 that previously was not - regression risk to existing architectures should therefore be negligible.

Note: Enabling a binary package for an architecture where it's known not to be useful - at last on it's own - is obviously non-ideal. I considered other options, but they all seem to add unnecessary regression risk:

- Demoting the "Depends:" to a "Recommends:". I actually think we should do this going forward (, but this would be a change in behavior to people who may install kdump-tools w/ Recommends-disabled and expect to stil get makedumpfile.

- Demoting only on arm64: This isn't possible unless we switch kdump-tools from Binary: any to Binary: all. I also think there are good reasons to do that in future releases (, but it seems overkill for just enabling arm64.

As today's version 1.5.9-5ubuntu0.1, there is already arch/arm64.c available, but it's still not included in debian/control. It does build in my arm64 docker env, haven't tried yet.

description: updated

Hello Matthias, or anyone else affected,

Accepted makedumpfile into xenial-proposed. The package will build now and be available at in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See 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, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at . Thank you in advance!

makedumpfile (1:1.5.9-5ubuntu0.5) xenial; urgency=medium

  * Build on arm64. While this version of makedumpfile doesn't support
    creating filtered dumps of Ubuntu arm64 kernels, it does satisfy
    the dependency for kdump-tools, which will cleanly fallback to 'cp'
    mode if makedumpfile fails. LP: #1238110, LP: #1694859.
