The following changes were introduced in Tails 2.7:

  • Fix multi-architecture support in Synaptic. This should fix broken installations of additional packages from Synaptic. (#11820)

  • Set default spell checking language of Icedove to English instead of French. (#11037)


New Tails Greeter

After many months of development, the redesigned version of Tails Greeter is ready to be tested.

Tails based on Debian 9 (Stretch)

We made lots of progress on porting Tails to Debian 9 (Stretch). This work culminated with the release of Tails 3.0~alpha1.

Reproducible ISO build

We had an initial sprint about reproducible builds. We are very happy with the progress we've made: the tree that becomes filesystem.squashfs is now almost fully reproducible; so is also the tree that is the basis for automatic upgrades. Along the way, we've contributed a number of patches to Debian and upstream projects.

  • Make our PO files update reproducibly, by not updating them unless something other than POT-Creation-Date has changed.
  • live-build:
    • Use xorriso, that honors the SOURCE_DATE_EPOCH variable, to build the ISO filesystem reproducibly.
    • Expose the SOURCE_DATE_EPOCH variable when running scripts inside the chroot.
    • Clamp mtimes to SOURCE_DATE_EPOCH in the chroot and binary filesystems.
    • Use SOURCE_DATE_EPOCH to populate /.disk/info timestamp.
    • Use SOURCE_DATE_EPOCH when templating syslinux templates.
  • Made mksquashfs honor SOURCE_DATE_EPOCH for the filesystem creation date, and had it clamp mtimes to SOURCE_DATE_EPOCH.
  • Incremental upgrade kits:
    • Made aufs white-outs reproducible.
    • Made aufs pseudo-links permanent, so that they are reproducible.
    • Passed --sort=name --clamp-mtime --mtime=@$SOURCE_DATE_EPOCH to tar.
  • Made our web site build reproducibly… and then discovered more bits that are not generated in a deterministic way, which lead us to discover that our cleanall build option did not clean as well as it should (fix).
  • Eliminated various causes for non-determinism, such as caches and other generated files.
  • On the infrastructure side of things:
    • Vagrant boxes management: we came up with a new design that will be reflected on the blueprint shortly.
    • Experimented with using our Vagrant + libvirt build system on one of our Jenkins ISO builders, and started work towards migrating them all.

Documentation and website

  • Explain why it is impossible to connect to GMail from Icedove.

  • spriver updated our documentation on shutdown and OpenPGP Applet to 2.0.

  • Chris Lamb fixed a bunch of typos.

User experience


  • The deployment of our mechanism for the distribution and activation of the revocation certificate of the Tails signing key has progressed a lot and it is now operational. Thanks to everybody who accepted being part of this!

  • We finished deploying our new infrastructure of download mirrors which allows for more mirrors, easier maintenance, and more flexibility in the future.

  • Our test suite covers 213 scenarios, 4 more that in October.


  • We continued our donation campaign and wrote about what we do with our money and our plans for the coming years.

  • Our grant proposal for NLnet on porting Tails to Debian Stretch was rejected.

  • Our grant proposal for ISC Project on a translation platform for our website was rejected.
