How to deal with the official website

Cause

• yumdb may be corrupted
• Language environment is not UTF-8

Countermeasures

If you can't do 1, do 2

1. Erase yumdb

bash

mv /var/lib/yum/yumdb/ /tmp
yumdb sync

2. Change python default encoding

Apparently yum is like a python script.

python

vi /usr/lib/python2.7/site-packages/sitecustomize.py

import sys
sys.setdefaultencoding("utf-8")

Conclusion

RedHat is bad because it wasn't CentOS.
