[Bug 1739991] Re: error processing archive (--unpack): unable to open '<FILE>.dpkg-new': Operation not permitted

I can confirm this bug on a machine.
Ubuntu version: 17.10.

I tried to install texlive/kile etc.
The first error occured on "oxygen-icon-theme_5%3a5.38.0-0ubuntu1_all.deb", which has been reported already at https://askubuntu.com/questions/975837/apt-dpkg-error-ubuntu-17-10

After trying out several things, I could install oxygen, however, other
packages were affected as well.

I do not think that this is a duplcate of bug #1685984, because this one
is more general.

Title:
  error processing archive (--unpack): unable to open '<FILE>.dpkg-new':
  Operation not permitted

Status in dpkg package in Ubuntu:
  Confirmed

Bug description:
  dpkg has failed to install or upgrade certain packages recently, with
  the following (sample) output:

  Unpacking linux-image-4.13.0-21-generic (4.13.0-21.24) over (4.13.0-21.24) ...
  Preparing to unpack .../linux-image-extra-4.13.0-21-generic_4.13.0-21.24_amd64.deb ...
  Unpacking linux-image-extra-4.13.0-21-generic (4.13.0-21.24) ...
  dpkg: error processing archive /var/cache/apt/archives/linux-image-extra-4.13.0-21-generic_4.13.0-21.24_amd64.deb (--unpack):
   unable to open '/lib/modules/4.13.0-21-generic/kernel/drivers/scsi/sym53c8xx_2/sym53c8xx.ko.dpkg-new': Operation not permitted
  [1]    18746 segmentation fault  sudo apt install -f
                                                      % 

  This problem appears seemingly at random, and has already occurred
  several times. apt will sometimes segfault, but other times report
  that dpkg errored. Repeatedly running the command results in a
  different file being shown every time, seemingly sequentially.
  Removing the whole directory tree and retrying does not solve the
  problem.

  Ubuntu version: 17.10
  What was supposed to happen: linux-image-4.13.0-21-generic getting installed successfully
  What happened instead: apt segfaulted after dpkg failed to write to a file
