问题的产生

在安装一个软件的Linux版本，有32位和64位的，我选择了64位，官方给的安装手册里就提到了没有文件夹可以手动创建，其它均没有提示，解压进入目录运行安装就会报错

pacman

在互联网上发现了类似的错误，如Index» Pacman & Package Upgrade Issues» Fontconfig related problem after last update的pacman更新的时候产生了这个问题，这个时候我看评论里面有说安装 lib32-fontconfig 2.13.0+10+g58f5285-1.1 就可以解决了，我用apt看了一下我已经安装了 fontconfig 2.13.1-2，没找到lib32-fontconfig和g58f5285 这两个包，于是我想更新下fontconfig。。

$ sudo apt upgrade fontconfig

升级了 154 个软件包，新安装了 5 个软件包，要卸载 0 个软件包，有 0 个软件包未被升级。
需要下载 536 MB 的归档。
解压缩后会消耗 284 MB 的额外空间。
您希望继续执行吗？ [Y/n] y

升级fontconfig失败，因为已经是最新的了，升级了相关的软件包之后还是安装同样的错误。

后遗症

每次开机默认进入deepin linux都会有这个问题，点击ok就开业进入os了，但是很烦，查了相关的论坛不是恢复默认设置就是关闭Secure Boot。em我这也没有对BIOS做了啥呀。。

fontconfig

在其它论坛看到不少相关的帖子，但是没从留言区找到解决办法。。
