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.

After this, I checked for the selinux file under /etc/sysconfig but I couldn't find it.

Also, when I tried

$ setenforce 1

it returns:

setenforce: SELinux is disabled

What are the dependencies? What should I download? How can I resolve this?

It looks like you don't GRUB (bootloader). I guess SELinux requires some changes in kernel so install your system with GRUB. Than installing SELinux just by 'apt-get install selinux' is correct.

How to Install SELinux on Ubuntu 18.04, Finally, we will install needed SELinux-related packages. This is to ensure we can work with the latest SELinux commands. Installing Apache and� When enabling SELinux on a Xen domU instance be sure to include an /etc/fstab entry for your root file system. Programs like fixfiles rely on the output from the mount command to report the file system type. Without an /etc/fstab entry mount will report the file system type as rootfs and fixfiles will fail silently.

Running SELinux under a Linux distribution requires three things: An SELinux enabled kernel, SELinux Userspace tools and libraries, and SELinux Policies. I'm guessing either your Kernel was compiled without the SELinux option enabled, and/or an issue related to your bootloader (grub-pc). This is from the Kernel docs.

If you want to use SELinux, chances are you will want to use the distro-provided policies, or install the latest reference policy release from http://oss.tresys.com/projects/refpolicy

However, if you want to install a dummy policy for testing, you can do using 'mdp' provided under scripts/selinux. Note that this requires the selinux userspace to be installed - in particular you will need checkpolicy to compile a kernel, and setfiles and fixfiles to label the filesystem.

  1. Compile the kernel with selinux enabled.
  2. Type 'make' to compile mdp.
  3. Make sure that you are not running with SELinux enabled and a real policy. If you are, reboot with selinux disabled before continuing.
  4. Run install_policy.sh: cd scripts/selinux sh install_policy.sh

Step 4 will create a new dummy policy valid for your kernel, with a single selinux user, role, and type. It will compile the policy, will set your SELINUXTYPE to dummy in /etc/selinux/config, install the compiled policy as 'dummy', and relabel your filesystem.

A Beginner's Guide to SELinux on CentOS 7, Getting Started with SELinux - Installation. Packages needed for an install of the new SE Linux on Debian unstable are as follows. You don't need to boot with � SELinux Modes SELinux has three basic modes of operation, of which Enforcing is set as the installation default mode. There is, however, an additional qualifier of targeted or mls which control how pervasive SELinux rules are applied, with targeted being the less stringent level.

I suggest to uninstall AppArmor because it may conflict with SELinux:

Remove apparmor Remove apparmor-util

Comments
  • What changes in the kernel are required? SELinux is baked into the kernel for all Ubuntu kernels.
  • Few years ago there were just several Linux distro that had been supporting SELinux. Now, 2017, it is natively present in most of well-known distros, I think. Just make sure if it is enabled or disabled.
