Title:
  4.7-3ubuntu0.16.04.2 vs 4.7-3ubuntu0.16.04.3 regression bug

Status in libtasn1-6 package in Ubuntu:
  Invalid

Bug description:
  I have downloaded and installed
  Armbian_5.35_Orangepizero_Ubuntu_xenial_next_4.13.16.img
  in an orange pi zero (256M, cheapest version)

  Then, I have setup WS2811; here my tutorial:
  http://www.orangepi.org/orangepibbsen//forum.php?mod=viewthread&tid=3318&page=1&extra=#pid21903
  which can be shortened to: edit /boot/armbianEnv.txt, add this
  param_spidev_spi_bus=1
  param_spidev_max_freq=100000000
  reboot, and check /dev/spidev1.0 exists. The rest does not matter for this issue.

  I have let the opi on the whole night; then, rebooted, and then,
  /dev/spi* are all gone away. After downgrading libtasn1-6 (and loosing
  over 5 days in tracking the root problem) , that file is in again.

  *** Before downgrade:

       containing an array.

  reboot

  *** What guided me to this:

  Yesterday, I did some installations; but this logs continues this
  morning, at 6am, while I was sleeping:

  tail -n 100 /var/log/dpkg.log

  So the mess is around libtasn1-6 or libc-bin.

  I have searched the file updated by the new package:
  dpkg -L libtasn1-6
  and compared the changelog between current installed version, and the same file provided in the raw installation image: I have compared the local file in the live system, with the one inside
  Armbian_5.35_Orangepizero_Ubuntu_xenial_next_4.13.16.img
  /usr/share/doc/libtasn1-6/changelog.Debian.gz
  /usr/share/doc/libc-bin/changelog.Debian.gz

  this helped me finding:
  - the curent version
  - guess the version that was installed previously
  - google for apropriate words, and download the .deb corresponding to the previous version.

  *** In short:

  During the night, the system automatically updated from
  libtasn1-6_4.7-3ubuntu0.16.04.2_armhf.deb
  to
  4.7-3ubuntu0.16.04.3
  and, after that update, my /dev/spi* disapeared (after reboot). After reverting to 10.04.2, and reboot, file appears again.

  According to times and date, this is not related to cron.daily, but
  probably to cron.d/armbian-updates

  * I tag this as security update, because, the security update must be
  REMOVED from servers before it breaks more machines.
