foreword
There should be many new Linux scholars like me who are not familiar with the basic syntax of Linux and encounter many problems when configuring the environment. For example, when downloading vim and other programs, if you use the officially configured apt source, the download speed is really fast unacceptable. Then we can actually replace the apt source and pip source with a domestic mirror website, so that the download speed will be the same as usual~ Take the mirror image of Tsinghua University as an example~
apt change source
The first step is to switch to super user mode.
In the second step, enter the following command to enter the sources.list file.
sudo gedit /etc/apt/sources.list
The third step is to go to the open source website of Tsinghua Mirror.com , select your ubuntu version, for example, mine is 20.04, and then copy the content of the text box. As shown below.
Step 4: After copying the content of deb..., replace all the sources.list file with the content just copied, and save it.
Step five, update apt using the command below.
sudo apt-get update
Finally, update the application using the command below.
sudo apt-get uograde
vim download
After updating the apt source, you can quickly download vim directly using the following command.
sudo apt install vim
test-vim
vim test.txt
install pip
sudo apt-get install -y python3-pip
Check pip version
pip3 -V
pip change source
