Set HTTP proxy for apt-Get

You can set HTTP proxy for apt-get in three ways.
Method 1
This is a temporary method. If you only need to use apt-Get through HTTP Proxy temporarily, you can use this method.
Before using apt-Get, enter the following command in the terminal (replace yourproxyaddress and proxyport according to your actual situation ).
Export http_proxy = http: // yourproxyaddress: proxyport
Method 2
This method requires the apt. conf file in the/etc/APT/folder. If you want apt-Get (instead of other applications) to always use HTTP proxy, you can use this method.
Note: In some cases, the apt configuration file is not created during system installation. The following operations modify the existing configuration file or create a new configuration file as needed.
Sudo gedit/etc/APT/apt. conf
Add the following line to your apt. conf file (replace yourproxyaddress and proxyport according to your actual situation ).
Acquire: http: proxy "http: // yourproxyaddress: proxyport ";
Save the apt. conf file.
Method 3
This method adds two lines to the. bashrc file in your home directory. If you want apt-Get and other applications such as wget to use HTTP proxy, you can use this method.
Gedit ~ /. Bashrc
Add the following content at the end of your. bashrc file (replace yourproxyaddress and proxyport according to your actual situation ).
Export http_proxy = http: // yourproxyaddress: proxyport
Save the file. Close the current terminal and open another terminal.
Use apt-Get update or any network tool you want to use to test the proxy. I use firestarter to view active network connections.
If you modify the configuration file again to correct the error, close the terminal and open it again.
