APT Proxy

可实现一些国内访问较慢第三方 apt 源的加速下载 (如 Syncthing)

下文同样以 Syncthing 源为例.

寻找配置位置

Ubuntu / Debian 高版本可查找 /etc/apt/sources.list.d/ 下文件, 或自行搜索

# From apt.syncthing.net
# Add the "stable" channel to your APT sources:
echo "deb [signed-by=/etc/apt/keyrings/syncthing-archive-keyring.gpg] https://apt.syncthing.net/ syncthing stable" | sudo tee /etc/apt/sources.list.d/syncthing.list

操作完成后可编辑 /etc/apt/sources.list.d/syncthing.list:

# original
#deb [signed-by=/etc/apt/keyrings/syncthing-archive-keyring.gpg] https://apt.syncthing.net/ syncthing stable

# added proxy:
deb [signed-by=/etc/apt/keyrings/syncthing-archive-keyring.gpg] https://your.proxy/https://apt.syncthing.net/ syncthing stable # 将 your.proxy 改为你自己的代理地址
# 如果有 signed-by 标签, 保留即可

修改完成后保存文件, 执行 apt update 测试

此时可能出现两种情况:

1

# ...
获取:6 https://xxxxxxxxxx/https://apt.syncthing.net syncthing InRelease [15.1 kB]
获取:8 https://xxxxxxxxxx/https://apt.syncthing.net syncthing/stable arm64 Packages [1,579 B]
# ...

能正常更新代表配置成功, 你可以退出此教程了.

2

出现类似提示: 由于没有公钥，无法验证下列签名：xxx

解决方法:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys xxx

将 xxx 改为你报错中的 key (一个 16 进制值)

重新运行 apt update, 问题应已解决.
