Centos 5 update 一直出現問題如下
po = self.pc(repo, cur.fetchone())
File "/usr/lib/python2.4/site-packages/yum/sqlitesack.py", line 68, in __init__
self._read_db_obj(db_obj)
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
[root@mail1 ~]# yum clean metadata

另一台 yum update 出現 perl 5.58 suidperl update error
ref CentOS update perl makes MailScanner fail 仍不行
