Behind proxy, ubuntu:devel apt-get update crashes on APT::Update::Post-Invoke 'rm -f /var/cache/apt/archives/*.deb /var/cache/apt/archives/partial/*.deb /var/cache/apt/*.bin || true'

[dualBootLaptop]

When behind a proxy, running apt-get update on ubuntu:devel fails.

ubuntu:rolling works fine.

All the proxy settings are properly set, specifically using https://gitlab.com/shell-bootstrap-scripts/network-settings , so that apt-get update works fine on ubuntu:rolling. If you like, you can copy https://gitlab.com/shell-bootstrap-scripts/network-settings behind a proxy (and change the proxy settings to the appropriate settings) to reproduce.

The output from ubuntu:devel is

E: Sub-process returned an error code

The output from ubuntu:rolling is as expected.

Thank you for the report.

This issue is actually not related to proxy settings (albeit the confusing error message); rather, it was a problem with our container stack and the newer glibc on Ubuntu Impish. We are working on this bug:

https://bugs.launchpad.net/cloud-images/+bug/1943049

It has been fixed on Ubuntu Impish (which means that if your host is running Impish, you will be able to run "apt-get update" inside an ubuntu:devel image), but the fix hasn't landed on Ubuntu Focal/Bionic/Hirsute yet. I am assuming you're using one of those 3 versions of Ubuntu as your host.

I will mark this bug as a duplicate of #1943049, but let me know if you think this is a different issue (in which case I'd kindly ask that you provide further steps to reproduce it).

Thanks.
