存储库未在 docker build 中签名 [英] Repository is not signed in docker build
问题描述
我有以下使用从 dockerhub 拉取的最新 Ubuntu 镜像的 Dockerfile:
I have the following Dockerfile that uses the latest Ubuntu image pulled from dockerhub:
FROM ubuntu:latest
RUN apt-get update && apt-get install -y g++ llvm lcov
当我启动 docker build 命令时，出现以下错误:
when I launch the docker build command, the following errors occur:

我在这里阅读 https://superuser.com/questions/1331936/how-can-i-get-past-a-repository-is-not-signed-message-when-attempting-to-upgr您可以使用 --allow-unauthenitcated 或 --allow-insecure-repositories 传递此错误，但在我看来，这两种解决方法都可能危及容器的安全性.
I read here https://superuser.com/questions/1331936/how-can-i-get-past-a-repository-is-not-signed-message-when-attempting-to-upgr that you can pass this error using --allow-unauthenitcated or --allow-insecure-repositories but both seem to me workarounds that may compromize security of the container.
编辑
尝试以不同的发行版名称拉取 ubuntu:18.04、ubuntu:19:04、ubuntu:19.10 相同的错误
Tried to pull ubuntu:18.04, ubuntu:19:04, ubuntu:19.10 same error with different distro name
推荐答案
显然我的根分区已满(可能是我尝试了太多次无法通过 apt 下载软件包)，然后运行 sudo apt clean 解决了问题
Apparently my root partition was full (maybe I've tried too many times to download packages through apt), and running sudo apt clean solved the issue
