Changing Ubuntu’s Package Mirror
On a Tencent Cloud Ubuntu instance, installing packages with apt failed because the configured mirror could not be resolved:

Switching the package mirror resolved the problem in this setup.
Back up the source list
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bkOpen sources.list
sudo vi /etc/apt/sources.listAdd the Aliyun mirror entries
I added these entries at the beginning of /etc/apt/sources.list. They are for Ubuntu 18.04 Bionic, the release used in this November 2022 post:
