yum: Nothing to do linux

系统为centos7，在安装wget时，执行命令：yum -y install wget，提示如下错误：

Loaded plugins: langpacks, versionlock Excluding 1 update due to versionlock (use "yum versionlock status" to show it) Package wget-1.14-18.el7_6.1.x86_64 already installed and latest version Nothing to do

根据提示猜测是，wget已经安装但没有正常启动，所以就先删除再重新安装，删除执行如下：

yum remove -y wget-1.14-18.el7_6.1.x86_64

执行成功后，再执行安装wget操作，命令如下：

yum install wget -y

【yum: Nothing to do】安装成功，如下：
