W: Some index files failed to download. They have been ignored, or old ones used instead.
and I have done my proxy setting in file .bash_profile like:
function setproxy
{
export {http,ftp}_proxy=xx.yy.com:80
} function unsetproxy
{
unset {http,ftp}_proxy
} setproxy
and check it with command env | grep -i proxy:
kay@cn:~$ env | grep -i proxy
http_proxy=xx.yy.com:80
ftp_proxy=xx.yy.com:80
At last, I found what I should do is to create an apt proxy conf file.
Apt loads all configuration files under /etc/apt/apt.conf.d. We can create a configuration specifically for our proxy there, keeping it separate from all other configurations.
Create a new configuration file named proxy.conf.
sudo touch /etc/apt/apt.conf.d/proxy.conf
Open the proxy.conf file in a text editor.
sudo vi /etc/apt/apt.conf.d/proxy.conf
Add the following line to set your HTTP proxy.
Acquire::http::Proxy "http://user:password@proxy.server:port/";
Add the following line to set your HTTPS proxy.
Acquire::https::Proxy "http://user:password@proxy.server:port/";
Save your changes and exit the text editor.
Your proxy settings will be applied the next time your run Apt.
