curl 設(shè)置 代理
sudo curl -x “http://192.168.1.2:3128”

需要驗(yàn)證的代理
sudo curl -x “http://username:password@192.168.1.2:3128”

另一種臨時(shí)代理

export http_proxy=http://<proxy>:<port>
export https_proxy=http://<proxy>:<port>
sudo -E add-apt-repository ppa:linaro-maintainers/toolchain

https://askubuntu.com/questions/53146/how-do-i-get-add-apt-repository-to-work-through-a-proxy

如果沒有代理配置文件就創(chuàng)建一個(gè)
sudo touch /etc/apt/apt.conf.d/proxy.conf

編輯配置
sudo vim /etc/apt/apt.conf.d/proxy.conf

Acquire::http::Proxy "http://[username]:[password]@ [proxy-web-or-IP-address]:[port-number]";
Acquire::https::Proxy "http://[username]:[password]@ [proxy-web-or-IP-address]:[port-number]";

輸入 sudo apt update 測(cè)試

設(shè)置清華源

Ubuntu 的軟件源配置文件是 /etc/apt/sources.list。將系統(tǒng)自帶的該文件做個(gè)備份，將該文件替換為下面內(nèi)容，即可使用選擇的軟件源鏡像。

# 默認(rèn)注釋了源碼鏡像以提高 apt update 速度，如有需要可自行取消注釋
