在 centos 5.3 下執行 yum update
最後會出現一長串的錯誤訊息：
Traceback (most recent call last):
File “/usr/bin/yum”, line 29, in ?
yummain.user_main(sys.argv[1:], exit_code=True)
File “/usr/share/yum-cli/yummain.py”, line 229, in user_main
errcode = main(args)
…
File “/usr/lib/python2.4/site-packages/yum/sqlitesack.py”, line 94, in _read_db_obj
setattr(self, item, _share_data(db_obj[item]))
TypeError: unsubscriptable object

解決方式如下：
[root@JNT ~]# yum clean all
Loaded plugins: security
Cleaning up Everything
[root@JNT ~]# rm -f /var/lib/rpm/__db*
[root@JNT ~]# rpm –rebuilddb
[root@JNT ~]# yum update
…
成功!!!
