This issue only affects the upgrade itself.  If you've already updated,
there shouldn't be anything else you need to do.

If you're still seeing issues with cups starting even after the upgrade has
completed, then you have a different bug.

Title:
  https crashed with SIGSEGV in lookup_or_create_bucket()

Status in “apt” package in Ubuntu:
  Invalid
Status in “p11-kit” package in Ubuntu:
  Fix Released

Bug description:
  This happened after a slightly broken upgrade, but it can be
  reproduced with

  $ sudo cp /etc/pkcs11/modules/gnome-keyring-module /etc/pkcs11/modules/gnome-keyring-module.dpkg-new
  $ sudo apt-get update
  p11-kit: duplicate configured module: gnome-keyring-module: /usr/lib/x86_64-linux-gnu/pkcs11/gnome-keyring-pkcs11.so
  E: Method https has died unexpectedly!
  E: Sub-process https received a segmentation fault.

  There are two bugs here, I suppose.  One is that pkcs11 should ignore
  *.dpkg-new files (usually this would be done by reading, e.g.,
  /etc/pkcs11/modules/*.conf instead of /etc/pkcs11/modules/*), and the
  other is that a duplicate file shouldn’t cause a crash.
