Question

我正在使用Ubuntu Docker镜像：ubuntu:14.04

我想使用以下方式更新我的树：

RUN apt-get  update

但我一直收到这个错误：

W: GPG error: http://archive.ubuntu.com trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/binary-amd64/Packages  Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead.

我尝试了多种方法，包括apt-get clean和RUN rm -R /var/lib/apt/lists/* -vf

他们都没有解决问题。

任何想法如何忽略此错误并继续构建容器？

It is possible you have an outdated version of Ubuntu in your image cache. Run docker pull ubuntu:14.04 to make sure you have the latest version present.

apt-get update should work out of the box; if it's not working, something else is wrong (possibly a caching mirror that's out of date, or a proxy server causing issues).

Also, to skip docker's caching mechanism during a build, you can use the --no-cache option; docker build --no-cache .

就我而言，这是由于我的 mac 上的屏幕时间。（为什么 tf 在 MacOS 安装时自动启用？？）。无论如何，前往设置，找到屏幕时间，然后禁用该死的东西。希望这能帮助一些可怜的 Mac 用户损失很多时间。

尝试在dockerfile中RUN apt-get update之前添加此内容：

RUN gpg --keyserver subkeys.pgp.net --recv 16126D3A3E5C1192
RUN gpg --export --armor 16126D3A3E5C1192 | sudo apt-key add -
