Failed to set locale, defaulting to C.UTF-8 报错

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

Failed to set locale, defaulting to C.UTF-8 报错

安装语言包

yum -y install glibc-langpack-en

再次查看

Failed to set locale, defaulting to C.UTF-8 报错

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

[root@localhost /]# yum -y install kde-l10n-Chinese
