How To Install SELinux on Ubuntu 8.04 “Hardy Heron”

By | 2008/03/18

I’m really happy to announce that SELinux is now available in Ubuntu 8.04 “Hardy Heron”.  This is the result of the amazing work of the ubuntu-security and ubuntu-hardened teams, as well as the huge contributions from the folks at Tresys.  (note: SELinux will not be the default, but is available as a security option.)

If you would prefer to use SELinux over AppArmour, or if you’re just a good soul that would like to help test Ubuntu’s SELinux implementation, please read on.

Install SELinux in Ubuntu 8.04

All that is needed is to install the SELinux package, which will remove AppArmour and apply the SELinux policy.

sudo apt-get install selinux

If you run across any issues or bugs please report them against SELinux on launchpad. Welcome to a more secure Ubuntu!

    The link to SELinux on Launchpad is broken.

    Taken from “”:
    “If using aptitude instead of apt-get, you will need to manually remove apparmor and apparmor-utils, deselect selinux-policy-dummy, and then choose selinux-policy-refpolicy.”

    Why does it want to replace 2.6.24-12-generic with 2.6.22-14-xen?

    I don’t want to downgrade to 2.6.22…

    I tried to install SELinux on Hardy SERVER (Release Candidate). However, I got the following error:

    Setting up selinux (0.2) …
    Unknown terminal: dtterm
    Check the TERM environment variable.
    Also make sure that the terminal is defined in the terminfo database.
    Alternatively, set the TERMCAP environment variable to the desired
    termcap entry.
    debconf: whiptail output the above errors, giving up!
    dpkg: error processing selinux (–configure):
    subprocess post-installation script returned error exit status 255
    Setting up selinux-policy-refpolicy-unconfined (0.0.20071214-0ubuntu3) …

    Errors were encountered while processing:
    E: Sub-process /usr/bin/dpkg returned an error code (1)

    TERM is not set properly or Linux does not support your terminal

    Sorry for the lack of knowledge but this is open source, right? How in the world could that be a backdoor?!

      The CIA or the NSA has planted an agent in the development team.

    when i tyr the command “aptitude install selinux” the system shows:

    Couldn’t find package “selinux”.However the following packages contain “selinux” in their name: libselinux1

    What’s the matter?

    No backdoor. NSA doesn’t want your data, they already have it. They just want to deny others access to your data.

    This a line of my system log. Why does it say REDHAT ????

    Mar 9 11:14:03 boss-desktop dhcdbd: message_handler: message handler not found under /com/redhat/dhcp/eth0 for sub-path eth0.dbus.get.host_name

    Is SELINUX for a desktop or for a server?

    Please clarify if this is normal.

      @Mir – SELinux is commonly used in both environments, both Desktop and Server. The error you’re getting doesn’t look related to SELinux though. Its coming from dhcpd.
