【问题描述】：
我在 docker 内更新 apt 时遇到问题。目前我已经将整个 dockerfile 注释掉了，除了这个：
FROM ubuntu:18.04
RUN apt update
基本上我必须先做apt update，因为没有它，ubuntu 包管理器将无法工作。但是，这条线打破了我的 docker 构建：
(pyomexmeta-test) ciaran@DESKTOP-K0APGUV:/mnt/d/libOmexMeta$ DOCKER_BUILDKIT=1 docker build -t pyomexmeta:v-0.0.13 .

failed to solve with frontend dockerfile.v0: failed to build LLB: executor failed running [/bin/sh -c apt update]: runc did not terminate sucessfully
(pyomexmeta-test) ciaran@DESKTOP-K0APGUV:/mnt/d/libOmexMeta$ echo $http_proxy
我也试过不使用 DOCKER_BUILDKIT=1 变量，结果相同（尽管速度较慢）。
我猜这是一些基本的东西，因为我是 docker 新手，但是有人可以建议我如何更新 apt 而不会破坏我的构建？
【问题讨论】：

你在代理后面吗？或者你可以试试
FROM ubuntu:18.04 RUN apt-get update或RUN apt-get -o Acquire::Check-Valid-Until=false -o Acquire::Check-Date=false update -
这真的很奇怪 - 使用
apt-get update有效，但apt无效。我的印象是它们是同一回事。无论如何 - 谢谢，当然不会单独想出那个。
