Comment 1 for bug 1952803

I'm able to reproduce the problem from a python shell and it appears that the custom-root/etc/apt/apt.conf.d/local file has 640 permissions so the cubic process (run as "me") can't access it.

In the script I run within the chroot I added a step to "chmod o+r /etc/apt/apt.conf.d/local" and that resolves the issue for me.

I'm not sure why I didn't have this issue with 2021.11-61 since I was running the same script in the chroot shell.
