## 编辑配置文件

```bash
sudo vim /etc/apt/apt.conf.d/proxy.conf 
```

## 写入配置

```conf
Acquire::http::Proxy "http://user:password@proxy.server:port/";
Acquire::https::Proxy "http://user:password@proxy.server:port/";
```

或者

```conf
Acquire {
  HTTP::proxy "http://127.0.0.1:8080";
  HTTPS::proxy "http://127.0.0.1:8080";
}
```

> 虽然不一定总能找 APT 镜像源，但我们还是可以用魔法打败魔法。

## 快速附魔

可以写一个脚本来`启用`/`禁用` proxy

### 创建脚本文件

```bash
sudo vim /usr/local/bin/apt-proxy
```

### 写入脚本

```bash
#!/bin/bash
if [ "$1" == "off" ]
then
rm -rf /etc/apt/apt.conf.d/proxy.conf
echo "apt's proxy removed"
else
echo 'apt proxy on'
PROXY=${1:-"<DEFAULT_PROXY_URL>"}
cat <<EOT > /etc/apt/apt.conf.d/proxy.conf
APT_PROXY='Acquire::http::Proxy "$PROXY";
APT_PROXY='Acquire::https::Proxy "$PROXY";
EOT
cat /etc/apt/apt.conf.d/proxy.conf
fi
```

### 添加运行权限

```bash
sudo chmod +x /usr/local/bin/apt-proxy
```
### 使用

```bash
# 为 apt 添加默认 proxy
sudo apt-proxy
# 为 apt 添加指定 proxy
sudo apt-proxy <PROXY_URL>
# 禁用 apt 的 proxy
sudo apt-proxy off
```
