In the Debian system to replace with domestic sources, you can follow the steps below:
- Back up the source list file: First, back up the current source list file by opening a terminal and running the following command as an administrator:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak- Edit the source listing file: Open the source listing file with a text editor such as nano or vim:
sudo nano /etc/apt/sources.list- Replace with domestic source: Replace the contents of the file with the appropriate domestic source for your region. Here are some examples of commonly used domestic sources:
