在kubuntu上安装软件

Question

我最近安装了kubuntu。我可以从μon软件中心安装软件。但是当我尝试从终端上这样做时，我会遇到错误。例如在尝试更新，我得到：

Err http://archive.canonical.com quantal InRelease 

Err http://archive.canonical.com quantal Release.gpg 
    Unable to connect to archive.canonical.com:http: 
Err http://archive.ubuntu.com quantal InRelease

W: Some index files failed to download. They have been ignored, or old ones used instead. 

类似的，当我尝试安装git的核心，我得到：

如何处理这个问题。如果有问题，我在代理服务器后面使用互联网。

Answer 1

您应该添加您的代理配置，以/etc/apt/apt.conf

Acquire::http::Proxy "http://proxy-ip-or-hostname:port"; 

如：

Acquire::http::Proxy "http://192.168.0.1:3128"; 

或认证

Acquire::http::Proxy "http://user:[email protected]:3128";
