The user provided a lot of details about the issue they're facing when installing certain packages within a Docker container using an ARM64 image on Ubuntu 20.04. + +First, let's break down what's happening. They're running a Docker container with an arm64v8/debian:bullseye base image on their host machine, which is Ubuntu 20.04 for AMD64. When they try to install 'wget', which depends on 'libc-bin', the installation process crashes with a segmentation fault from QEMU. + +The error message says "qemu: uncaught target signal 11 (Segmentation fault)". I know that a segmentation fault usually happens when a program tries to access memory it's not supposed to, which could be due to a bug in the software or a compatibility issue. + +Looking into the packages involved, they're using 'qemu-user-static' version 1:4.2-3ubuntu6.14 on Ubuntu 20.04. They mentioned that this bug has been fixed in Ubuntu 20.10's version of qemu-user-static but not backported to 20.04. This suggests it's a QEMU user-mode issue because they're using static QEMU user binaries for cross-architecture Docker support. + +The crash occurs during the installation of 'libc-bin', which is part of the base system libraries. Since this happens within the Docker container, and Docker uses QEMU to run ARM64 images on an AMD64 host, it's likely a translation issue in QEMU when executing certain instructions or accessing memory in user-space. + +They've linked to a Launchpad bug (https://bugs.launchpad.net/qemu/+bug/1749393), which is about a similar segmentation fault. The bug was fixed in later versions of QEMU, but the fix isn't available in Ubuntu 20.04's package. This points towards a user-mode translation issue because it affects how QEMU emulates the ARM64 instructions on an x86 host. + +Considering that the problem occurs during package installation within the container, which is handled by the user-space emulation provided by QEMU-user-static, this reinforces that it's a user-mode related bug. It doesn't involve system-level hardware interactions or higher privileges beyond what Docker typically uses for cross-architecture containers. + +Therefore, after evaluating the components involved and the nature of the crash, I conclude that this is a user-mode issue. +</think> + +user \ No newline at end of file |
