两小时前我尝试手动更新软件包。我的镜子中确实缺少 InReleasehttp://ftp.fr.debian.org/debian/dists/stretch/InRelease,也是来自CDN之一http://deb.debian.org/debian/dists/stretch/InRelease。
预计该 InRelease 文件会因拉伸而丢失吗?
me@stretch:~$ LANG=C sudo apt update

手动尝试 wget InRelease 文件(网络连接正常,如您所见):

答案1
如果你在码头工人您可以尝试重新启动 Docker 守护进程。
sudo systemctl restart docker
这为我解决了这个问题。
答案2
提到的唯一原因InRelease
是这是 apt 尝试下载的第一个文件。实际错误发生在以下之后:
暂时无法解析“ftp.fr.debian.org”
(“security.debian.org”也是如此)
像这样的错误会导致下载任何文件时出现问题,因此显然第一次会失败。
您应该查看您的网络配置以找出无法解析这些名称的原因。
答案3
在我的 Debian 系统上,我验证了:
- DNS解析我使用的debian镜像的ipv4 A和ipv6 AAAA记录(使用“dig”命令确认,默认DNS存储在resolv.conf中)
- 当尝试下载与 apt-get 相同的 URL 时,wget 成功
因此,独立于 apt,我的 Debian 系统没有 DNS 或互联网连接问题。但 apt 不断失败,即使在/etc/apt/source.list
.
我发现的唯一解决方法:直接在source.list
.
答案4
您需要从 切换deb.debian.org
到archive.debian.org
。
