Selinux installation seems incomplete..

[ninja123]

I am trying to download selinux on an Ubuntu 11.04 using apt-get.

when I tried sudo apt-get install selinux: I got the following error: The following packages have unmet dependencies: selinux : PreDepends: grub-pc but it is not installable E: Broken packages

I then downloaded selinux-utils, selinux-basics.
then, I tried setenforce 1 it returns: setenforce: SELinux is disabled

So, I checked for the config file under /etc/selinux which showed that
parameter SELINUX=permissive

However setenforce 0/1 always shows selinux disabled. I even tried to login as root and did: echo '1' > /selinux/enforce (actually under /selinux there were no parameters!!)

I even tried seinfo and it showed an error: Could not find policy file blah blah.

What are the dependencies? what should I download? how can I resolve this?


Pleas help

From what I read up until now, SElinux seems to be only marginally supported at Ubuntu:

Ubuntu has AppArmor and if you really want SELinux, it may be better to use Fedora, which has a really well integrated SELinux implementation.

See https://bugs.launchpad.net/ubuntu/+s...x/+bug/1047099 for the grub-pc removal issue

As 2F4U said, SELinux support is marginal at best. However, if you are really interested in it, the most relevant/current documentation is here:

I really wouldn't use SELinux with Ubuntu. If you're looking for SELinux try Fedora. Otherwise I think Apparmor is very useful for Ubuntu users.

I highly advise you select the distro based on what security tools you want.

Apparmor - Ubuntu and SUSE
Selinux - Fedora, RHEL, Centos, Scientific Linux
grsecurity - Gentoo (hardened)
