V3 DSA signature: NOKEY, NOKEY 错误解决

Redhad linux AS4下的GCC安装
1.进行linux第三张安装盘的RPMS目录。2.运行rpm -ivh glibc-kernheaders-2.4-9.1.87.i386.rpm安装glibc-kernheaders。3.运行rpm -ivh glibc-headers-2.3.4-2.9.i386.rpm安装glibc-headers。4.运行rpm -ivh glibc-devel-2.3.4.2.9.i386.rpm安装glibc-devel。5.运行rpm -ivh gcc-3.4.4-2.i386.rpm安装GCC。6.运行rpm -ivh gcc4-4.0.1-4.EL4.2.i386.rpm。7.运行rpm -ivh libstdc++-devel-3.4.4-2.i386.rpm。8.运行rpm -ivh gcc-c++-3.4.4-2.i386.rpm安装c++编译器。
今天给Linux AS 4 安装GCC 提示下面的错误提示


[root@localhost ~]# rpm -ivh glibc-headers-2.3.4-2.25.i386.rpm
warning: glibc-headers-2.3.4-2.25.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
error: Failed dependencies:
        glibc = 2.3.4-2.25 is needed by glibc-headers-2.3.4-2.25.i386

在后面加入 --force --nodeps    意识是忽略软件包及文件的冲突，不验证套件依赖性


[root@localhost ~]# rpm -ivh glibc-headers-2.3.4-2.25.i386.rpm --force --nodeps
warning: glibc-headers-2.3.4-2.25.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
