I installed selinux first, I set
SELINUX=enforcing instead of its original value,
/etc/selinux/config, then I reboot my computer.
I waited for some time, but it stopped, I rebooted again and it can not go into the system anymore so I restored the setting.
I tried to run
seinfo command in a terminal, but it output some errors below:
ERROR: policydb version 26 does not match my version range 15-24 ERROR: Unable to open policy /etc/selinux/ubuntu/policy/policy.26. ERROR: Input/output error
It seems that there is a little difference on how to start up selinux between CentOS and Ubuntu, can you help me configure selinux in Ubuntu?
