Question Q
When using yum to install software, you may encounter a problem of "no software package available". The reason for this problem is that the software package is in the third-party yum source, not in the official yum source.

Yum can’t find it. Maybe it’s because the source of this software is not available. Install Xu.
Answer 2
Install third-party library sources
sudo yum install epel-release
Answer 3
If you can't find the source, you need to see if the package name is entered incorrectly.
Answer 4
Install the source package manually
