Reproducible Builds: Weekly report #76

Published: Oct 10, 2016.

What happened in the Reproducible Builds effort between Sunday October 2 and Saturday October 8 2016:

Media coverage


  • Vagrant Cascadian gave an impromptu talk about reproducible builds at CAT Barcamp on 8th October.

  • Holger discussed Reproducible coreboot at Unlike other projects, coreboot doesn’t do binary releases because there have been many instances of people taking some incorrect coreboot binary, flashed it and bricked their machines… The end idea is that coreboot will simply release .buildinfo files (and still no binaries) instead.

Packages reviewed and fixed, and bugs filed

Weekly QA work

During of reproducibility testing, some FTBFS bugs have been detected and reported by:

  • Chris Lamb (12)


  • The data in reproducible-tracker.json (which is fed to tracker.d.o and DDPO) has been changed to contain data from testing as the build path variations we introduced for unstable are not yet ready for wider consumption. For testing/stretch we recomment to create reproducible packages by rebuilding in the same path. (h01ger)
  • Various reproducibility statistics for testing/stretch have been added to the dashboard view. (h01ger)
  • The repository comparison page has been improved to only show obsolete packages if they exist (which they currently don’t as we have rebuilt everything from the plain Debian repos, except for our modified dpkg due to #138409 and #787980). (h01ger)
  • All armhf boards are now using Linux kernels provided by Debian. (vagrant)


This week’s edition was written by Chris Lamb, Holger Levsen & Vagrant Cascadian and reviewed by a bunch of Reproducible Builds folks on IRC.
