yum 報錯與解決方案

1.錯誤：http://apt.sw.be/redhat/el5/en/i386/dag/repodata/filelists.xml.gz : [Errno -1] Metadata file does not match

checksum Trying other mirror.
Error: failure: repodata/filelist.xml.gz from dag: [Errno 256] No more mirrors to try.

解決：yum clean all

2.在使用yum 進行 install 時,錯誤
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 1ac70ce6
導致安裝不能進行。

解決：
[root@localhost CentOS]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
[root@localhost CentOS]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-beta
即匯入密鑰。
