Docker linuxserver.io/jellyfin multiarch 207：'exec 格式错误'

问题描述

我有一个问题，我不知道去哪里寻找问题。 我正在运行 debian:buster 并尝试将其设置为 jellyfin 服务器。

我添加了必要的架构 (amd64)。

user@server:~$ sudo dpkg --print-architecture
i386
user@server:~$ sudo dpkg --print-foreign-architectures
amd64
arm64

我根据 linuxserver.io/jellyfin 文档中的示例创建了一个 docker-compose 文件。

version: "2"
services:
  jellyfin:
    image: linuxserver/jellyfin:amd64-latest
    container_name: jellyfin
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=America/Chicago
      - UMASK_SET=022 #optional
    volumes:
      - /srv/jellyfin/cache/
      - /srv/jellyfin/config/
      - /media/nasdisk1/series/
      - /media/nasdisk1/films/
      - /media/nasdisk2/muziek/
    ports:
      - 8096:8096
      - 8920:8920
    restart: unless-stopped

当我执行 sudo docker-compose up 时，容器正在尝试重新启动并且容器的日志显示：

standard_init_linux.go:207: exec user process caused "exec format error"

当我查看守护进程的日志时，它有以下内容：

我在网上看到有人说这与架构有关，我也看到有人建议这与 dockerfiles 中的入口点有关。 我曾尝试过谷歌搜索，但我缺少有效执行此操作所需的参考框架。

这里出了什么问题？

解决方法

我通过询问一些聪明人找到了答案。

错误“exec format error”几乎总是指不支持的架构或其他问题。

使用 dpkg 来查看架构不是正确的方法。它显示了允许使用哪些架构安装的包。不是主机 CPU 架构是什么。

sudo dpkg --print-architecture
i386
user@server:~$ sudo dpkg --print-foreign-architectures
amd64
arm64

arch 命令显示主机 CPU 架构。

arch
i686

问题是 i686 是 32 位架构，而 jellyfin 和 linux 服务器只支持 64 位架构。 我不小心在我的系统上安装了 32 位 debian，而不是 64 位。
