Configuring the Linux software download source (Ubuntu)

because the default source of Ubuntu is foreign, download software is very slow, and often download failure, the following is mainly a way to add a domestic source as a software download source of the simple method.

1. Path to the configuration file for the software download Source:/etc/apt/sources.list

2. Add the download source address

(1) Open "Software&updates". Double-clicking the "sources.list" file directly also opens "Software&updates". The Display dialog box looks like this.

(2) Click "Other Software" and "Add ..." To open the dialog box below.

(3) Add the download source address you want to add to "APT line" and click "Add Source".

3. Update the source list

sudo apt-get update

sudo apt-get upgrade
