One-click replacement of Linux software source script: SuperUpdate.sh

Sometimes, Linux source updates are very slow, especially when using the default source in mainland China. Due to the network environment in mainland China, updates often fail and are slow. In this case, changing to a more suitable or closer or faster software source will make your Linux installation and update operations smoother and smoother. This script is suitable for CentOS 5, 6, 7, Ubuntu 14.04, 16.04, 18.04, Debian 7, 8, 9, one-click matching and source change.

Manually changing the source is also very simple. You only need to click a few steps to complete it. This script only completes these simple steps with one click, changing the software source for you faster. Although relatively simple, it can be a lot more convenient for people who manage multiple Linux servers or who often reinstall the system.

No more nonsense, the script is pure. In addition to modifying the software source files, no other files or configurations will be added, and other irrelevant settings will not be modified. There is no residue, and the code is not encrypted. This is also the principle of my script. , the function code only has about a hundred lines, please check yourself.
