apt 更新：无法握手：收到意外的 TLS 数据包

Question

我有问题做sudo apt update了手动添加存储库（我有问题，nodejs和docker）我Ubuntu 17.10 VM在跑步VirtualBox。我得到的错误是Could not handshake: An unexpected TLS packet was received。

以下是我在尝试添加docker存储库和输出时采取的步骤。当我尝试添加时也发生了同样的事情nodejs。

这是我的设置的详细信息：

   VM: Ubuntu 17.10
   VirtualBox 5.2.8 r121009 (Qt5.6.2)
   I am behind corporate proxy.

有谁知道如何解决这一问题？

Answer 1

检查是否也为 https 设置了代理。由于curl正在使用 https，我假设在某个地方https_proxy设置了一个变量（例如~/.bashrc）。apt需要/etc/apt/apt.conf或 中的代理配置/etc/apt/apt.conf.d/。您需要为所有协议指定代理：

# e.g. in file /etc/apt/apt.conf.d/05proxy
Acquire::http::proxy "http://192.168.0.1:3128/";
Acquire::https::proxy "http://192.168.0.1:3128/";
Acquire::ftp::proxy "http://192.168.0.1:3128/";

还要记住，如果只为sdnc-dev用户设置了代理配置，则需要sudo -E将环境暴露给 root 用户。

Answer 2

apt-get update我在使用Ubuntu 20.04 LTS时遇到了同样的错误。我在安装过程中配置了代理，这样代理网址就在/etc/apt/apt.conf.d/05proxy

就我而言，我错误地配置了代理 URL（对于我的组织），需要编辑05proxy并更改https://proxy.mydom.it为http://proxy.mydom.it

错误的配置：

Acquire::http::proxy "https://proxy.mydom.it:8080";
Acquire::https::proxy "https://proxy.mydom.it:8080";

好的配置：

Acquire::http::proxy "http://proxy.mydom.it:8080";
Acquire::https::proxy "http://proxy.mydom.it:8080";

在我的例子中，将 https 转换为 http 修复了 TLS 错误
