apt-get 升级：错误 503

Question

我坚持升级 Kubuntu 16.04。它开始升级，然后停止一段时间并给出错误 503。我尝试从 repo 手动下载文件，但尽管目录中存在文件，但我无法下载它们。apt-get clean并且apt-get upgrade --fix-missing也没有解决这个问题。我该如何解决这个错误？

编辑：尽管自服务器启动以来此问题已解决，但我认为不应搁置此问题，因为有些用户可能会遇到相同的问题并在此处找到解决方案。只是我的观点。

Answer 1

wine-staging-amd64_2.20.0~xenial_amd64.deb
wine-staging-i386_2.20.0~xenial_i386.deb

这些文件刚刚于 2017 年 11 月 6 日发布——它们要么存在一些网络问题，要么这些文件尚未完全传播。

运行这些命令不会有帮助：

sudo apt-get update
sudo apt-get upgrade

最好的解决方案是稍后重试，届时 503 错误就会自行解决。
