Ubuntu

修改 systemd service 的环境变量，可以通过 sudo systemctl status <service_name> 来找到 service file path.

然后修改环境变量：

[Service]
Environment=PATH=:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:

reload config 和重启 service

sudo systemctl daemon-reload 
sudo systemctl restart 

For normal linux cmd

Set this two lines on your .bashrc

export HTTP_PROXY=http://proxy.company.com:8080
export HTTPS_PROXY=https://proxy.company.com:8080

For cmd running under sudo

if you have to run sudo apt-get install, you have to pass the proxy config to root/sudo account

Edit /etc/sudoers and append below line to the file:

Defaults env_keep = "http_proxy https_proxy ftp_proxy DISPLAY XAUTHORITY"
