[英]apt-get install in Ubuntu 16.04 docker image: '/etc/resolv.conf': Device or resource busy
I'm getting the error message below when running apt-get install from within a rather vanilla Ubuntu 16.04 image:在相当普通的 Ubuntu 16.04 映像中运行 apt-get install 时,我收到以下错误消息:
ln: cannot remove '/etc/resolv.conf': Device or resource busy
dpkg: error processing package resolvconf (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
resolvconf
The packages seem to be installed correctly, though.不过,这些软件包似乎已正确安装。 How to fix it?如何解决?
My Dockerfile looks like this:我的 Dockerfile 看起来像这样:
FROM ubuntu:16.04
MAINTAINER Me Myself <me@myself.com>
RUN apt-get update && apt-get install -y git nano
RUN apt-get upgrade -y
# set the timezone. Note: there is an Ubuntu 16.04 bug which
# requires this to be done this way:
# http://stackoverflow.com/questions/40234847/docker-timezone-in-ubuntu-16-04-image/40235306#40235306
RUN ln -fs /usr/share/zoneinfo/Europe/Berlin /etc/localtime && dpkg-reconfigure -f noninteractive tzdata
RUN locale-gen en_US en_US.UTF-8 de_DE.UTF-8
ENV PATH="/opt/xyz/bin:${PATH}"
As mentioned in https://github.com/moby/moby/issues/1297 you can add the following line to your Dockerfile
:如https://github.com/moby/moby/issues/1297 中所述,您可以Dockerfile
添加到您的Dockerfile
:
RUN echo "resolvconf resolvconf/linkify-resolvconf boolean false" | debconf-set-selections
This way it is possible to install resolvconf
inside a container.这样就可以在容器内安装resolvconf
。
With the above comment and answer of @Christian Berendt, I still get these errors:根据@Christian Berendt 的上述评论和回答,我仍然收到以下错误:
debconf: unable to initialize frontend: Dialog
debconf: (TERM is not set, so the dialog frontend is not usable.)
debconf: falling back to frontend: Readline
debconf: unable to initialize frontend: Readline
debconf: (This frontend requires a controlling tty.)
debconf: falling back to frontend: Teletype
dpkg-preconfigure: unable to re-open stdin:
Here is my complete solution, by adding these lines into the Dockerfile:这是我的完整解决方案,将这些行添加到 Dockerfile 中:
These lines help install resolvconf withode debconf errors这些行有助于安装 resolvconf withode debconf 错误
RUN apt-get update
RUN apt-get install -y apt-utils debconf-utils dialog
RUN echo 'debconf debconf/frontend select Noninteractive' | debconf-set-selections
RUN echo "resolvconf resolvconf/linkify-resolvconf boolean false" | debconf-set-selections
RUN apt-get update
RUN apt-get install -y resolvconf
