To start I'm a complete noobie in the matter of SElinux and ubuntu, so my problem is that I tried installing it on ubuntu server 18.04 using this tutorial: https://www.linode.com/docs/quick-answers/linux/install-selinux-on-ubuntu/
But I cannot enable it either using setenforce or changing config file in selinux.
root@test:/# setenforce 1
setenforce: SELinux is disabled
If you need more info, I will gladly provide them.
Thank you in advance.
