to understand how annoying this has become,
when I try to install Synaptic Package Manager
error while installing package: unqble to open
'/usr/arm-linux-gnueabihf/lib/Mcrt1.odpkg-new

yet there is no obvious (to me) reason this is related in any way at
all.

Title:
  Bionic updates break upgrade (apt remove libc6-armhf-cross first)

Status in cross-toolchain-base package in Ubuntu:
  Triaged

Bug description:
  WORK AROUND: first, uninstall libc6-armhf-cross and libc6-armel-cross,
  then re-install the cross compiler package.

  As I reported in comments on the end of Bug #1769657 "update toolchain
  packages for bionic" on 5th October 2018 the updates have broken the
  ability to upgrade package(s). Specifically, the 'dpkg --unpack' stage
  breaks because, from what I can tell, some of the .dpkg-new files are
  being deleted before they are due to be renamed:

  $ sudo dpkg --unpack /var/cache/apt/archives/libc6-armhf-cross_2.27-3ubuntu1cross1.1_all.deb |& tee /tmp/dpkg-unpack.log

  $ apt-cache policy libc6-armhf-cross
  libc6-armhf-cross:

  I've analysed both failures using a combination of 'dpkg --debug
  77777', strace, and inotifywait, but I've not familiar enough with the
  dpkg logic to determine what is going wrong.

  I'm attaching debug, strace and inotifywait logs for 'libc6-armhf-
  cross' where 'ld-2.27.so.dpkg-new' appears to be the problem.
