答案1
我也有同样的问题,apt-get uses /etc/apt/apt.conf可用于代理设置,使apt.conf
匹配浏览器代理设置解决了这个问题。
/etc/apt$ cat apt.conf
Acquire::http::proxy"http://<proxy>";
Acquire::https::proxy"https://<proxy>";
Acquire::ftp::proxy"ftp://<proxy>";
Acquire::socks::proxy"socks:<proxy>";
答案2
这是我们大学网络的问题,问题仍然存在,其他WiFi网络工作正常。
答案3
当你发出这样的命令时,首先要确保DNS能够解析链接,我认为是这个问题。
sudo vim /etc/resolv.conf
确保使用google dns:
nameserver 8.8.8.8
重新启动networking.service
