我试图selinux在我的 librem14 pureos 机器上安装，每次运行时sudo apt-get install selinux-policy-default
我都会得到：
dpkg: error processing package selinux-policy-default (--configure):
installed selinux-policy-default package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
selinux-policy-default
E: Sub-process /usr/bin/dpkg returned an error code (1)
