Fedora下yum命令時出錯解決方法

yum安裝時出錯如下：

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897

    keys_info = misc.getgpgkeyinfo(rawkey, multiple=True)
  File "/usr/lib/python2.4/site-packages/yum/misc.py", line 377, in getgpgkeyinfo
    raise ValueError('No key found in given key data')
ValueError: No key found in given key data

解決方法：

使用時加--nogpgcheck可以解決，即yum --nogpgcheck install [軟件名]
