[Bug 1943049] Re: Docker ubuntu:impish: Problem executing scripts DPkg::Post-Invoke 'rm -f /var/cache/apt/archives/*.deb /var/cache/apt/archives/partial/*.deb /var/cache/apt/*.bin || true'

[Thomas Weise]

Hi.

I am sorry to ask this, but:
Has the solution already become available for "normal" users?
(If not, I can just wait a bit, no problem.)
What would I need to do to get it working on my system?

The reason why I am asking is that I have already updated my system just
now (apt-get update) and re-downloaded the ubuntu:21.10 image and my
duplicated bug as reported in https://bugs.launchpad.net/cloud-
images/+bug/1943293 still persists.

I am running Ubuntu 21.04 on my host system and use the ubuntu:21.10
container.

> sudo docker run --rm -it --entrypoint=/bin/bash "ubuntu:21.10"
# apt-get update && apt-get install -y curl
# curl https://www.bing.com
curl: (6) getaddrinfo() thread failed to start

Many thanks,
   Thomas.

P.S.: Argh, just now I see that under "affects", for "docker.io
(Ubuntu)", it just says "confirmed", not "fix released" ... that
explains it ^_^

Bug description:
  Sometime betweek August 28 and September 4 2021 the ubuntu:impish
  images published on dockerhub began erroring when executing the
  commands defined in /etc/apt/apt.conf.d/docker-clean.

  I have this reproducer, which is probably not as minimal as it can be
  but looks reliable:

  1. docker run -it --rm ubuntu:impish bash
  2. apt update
  3. apt install git
  4. apt -y remove git

  This results in:

  E: Problem executing scripts DPkg::Post-Invoke 'rm -f /var/cache/apt/archives/*.deb /var/cache/apt/archives/partial/*.deb /var/cache/apt/*.bin || true'
  E: Sub-process returned an error code

  *Removing* a package is not strictly needed to trigger the failure,
  but it seems that *two* apt operations are needed to trigger it, so
  this reproducer found by athos-ribeiro also works:

  docker run -it --rm ubuntu:impish /bin/bash -c 'apt-get update; apt-
  get full-upgrade -y; apt-get install -y jq'

  This doesn't happen when using ubuntu:hirsute.
