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:

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.
