    Selinux installation seems incomplete..

    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)
    There are two mistakes one can make along the road to truth...not going all the way, and not starting.
