Hello Martin,

Thank you for your message.

[Un]happily the bug 1560797, which seems to be Confirmed now, had for me 
no more consequences that a great amount of warning message during 
installation. The first reboot after installation was clean, and 
everything worked without problem after this.

So I'm afraid I won't be able to re-update from proposed, since my 
laptop works with xenial.
I hope other people affected by this bug won't experience more troubles 
than me.

Kind regards,
Christian

  SRU INFORMATION
  ===============
  Fix: https://anonscm.debian.org/cgit/apt/apt.git/commit/?id=c75e60eb (applied in Xenial last week)

  Test case:
   - Install clean wily amd64 desktop + install libgcrypt20:i386
   - change apt sources to xenial, apt-get dist-upgrade
   - with current apt, upgrade will often fail because systemd expects a configure libgcrypt20, or util-linux expects a configured libudev1 or similar, but these packages aren't configured.
   - with the fixed apt, the upgrade should run smoothly.

  Regression potential: Any bug here might potentially break package
  installation or upgrades completely. That said, the fix is quite
  obvious and has been in production in xenial for a week. Testing this
  SRU should include several dist-upgrades as well as some normal
  package installs in trusty/wily.
