Ubuntu 18.04 LTS replaces domestic sources
The ubuntu18.04 LTS download software is a bit slow. I searched the Internet for the solution. It is roughly to replace the source in the /etc/apt/sources.list file and change it to Alibaba Cloud or other mirrored files.
1. Change source-change the source in the /etc/apt/sources.list file
Change the source in the /etc/apt/sources.list file to Alibaba Cloud or other mirrored files
2. List of backup sources
The default source of Ubuntu configuration is not a domestic server, and downloading and updating software is relatively slow. First back up the source list file sources.list:
//首先备份源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
3. Open the sources.list file to modify
Select the appropriate source, replace the content of the original file, save the edited file, take Alibaba Cloud update server as an example (you can test the speed of Alibaba Cloud, Tsinghua University, University of Science and Technology, and 163 sources respectively, and choose the fastest):
// 打开sources.list文件
sudo gedit /etc/apt/sources.list
Edit the /etc/apt/sources.list file, add Alibaba Cloud mirror sources at the top of the file or delete all of them and add them:
Alibaba Cloud Source

After the change is completed, enter the update source, and run this to update the list before installing anything with apt.
sudo apt update
