问题
我试图Ubuntu的docker容器里安装libc6-dbg:i386,因为Valgrind需要使用它,但现在无法安装。
给出以下Dockerfile:
FROM ubuntu:14.04
MAINTAINER Me <xyz@example.com>
RUN apt-get update
RUN apt-get install libc6-dbg
RUN apt-get install libc6-dbg:i386
在Ubuntu 14.04桌面64位主机上:
sudo docker build .
我得到:

在主机上,我可以安装libc6-dbg:i386,为什么在Docker容器内无法安装它?

解决这个问题所需要的信息是https://wiki.debian.org/Multiarch/HOWTO。
官方docker ubuntu映像以及phusion/baseimage中的Apt仅配置了对amd64的支持。
# dpkg --print-architecture
amd64
# dpkg --print-foreign-architectures
<no output>
解决这个问题的方法是,在apt-get update之前添加另一个体系结构:
# dpkg --add-architecture i386
# apt-get update
<lots of lines>
# apt-get install libc6-dbg:i386

Do you want to continue? [Y/n]
为了完整性,下面是最终的Dockerfile:
FROM ubuntu:14.04
MAINTAINER Me <xyz@example.com>
RUN dpkg --add-architecture i386
RUN apt-get update
RUN apt-get install libc6-dbg
RUN apt-get install libc6-dbg:i386
答案2
尝试在apt-get update
前,在Dockerfile中添加以下行:
RUN echo"deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list
