背景：用Dokfile只做了镜像，启动容器后yum安装软件发现安装失败报错
报错提示：
[root@localhost /]# yum -y install kde-l10n-Chinese Failed to set locale, defaulting to C.UTF-8 Last metadata expiration check: 0:00:12 ago on Fri Jun 4 02:45:10 2021. No match for argument: kde-l10n-Chinese Error: Unable to find a match: kde-l10n-Chinese [root@localhost /]#
原因：通过报错可知是由于语言不对导致
查看语言环境
安装语言包
yum -y install glibc-langpack-en
再次查看
重新安装，报错消失，但依旧无法安装，检查后发现该安装包适配centos7，本系统为centos8，跟换后安装成功
