fedora10 yum install 错误：Package *.rpm is not signed

不知道是否是因为关闭了 selinux 的原因，突然间在使用 yum 安装时出现如下错误：

 

Package *.rpm is not signed

*.rpm 为应用程序包

 

解决方案是：更改 /etc/yum.conf 下的 gpgcheck=1 为 gpgcheck=0

 

关于 yum.conf 的详细可参考 man yum.conf。其中对 gpgcheck 的描述是：

gpgcheck
              Either  ‘1’  or ‘0’. This tells yum whether or not it should perform a GPG signature check on pack-
              ages. When this is set in the [main] section it sets the default for all repositories. This  option
              also  determines whether or not an install of a package from a local RPM file will be GPG signature
              checked. The default is ‘0’.
