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

[iczero]

Public bug reported:

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
