I have removed AppArmour for SELinux (available via the ubuntu-hardened PPA).

I tried to upgrade from a gutsy system to hardy alpha 5 and had a similar problem with cupsys 1.3.6-1ubuntu1 with kernel 2.6.24-10-generic. It couldn't find apparmor_parser, and failed.to configure In turn a lot of other dependencies failed. The upgrade failed, and suggested I return my system to it's original state, but I put it on a USB Boot in case I worked out how to stabilize it later Because I was going to try and install an ndiswrapper for the new kernel I started off with an apt-get install build-essential, While build-essential was already installed It gave me a good summary of the packages that failed to configure I'll attach it. I've posted it to an upgrade bug that was invalidated because I have a Ubuntu Ultimate system, but this time I can be more specific.

i still regularly get this issue with any update of cups. I was assuming it was related to my addition of SELinux / removal of apparmor?

[pokkets (pokkets1)]

I haven't been sure if it was the upgrade as much as the number of applications I have loaded on my system. I decided to try and load as much as I could onto my system , because I intend to upgrade my laptop, to a dual core, before I installed a system permanently on the new laptop. I now know I 'experiment' to much to have a permanent stable system. but being new to linux and ubuntu I wanted to learn as much as quickly as possible. The 'hard way' can make learning both necessary, and memorable. I hadn't done anything with apparmor, or tried to install SELinux - yet. I haven't been able to connect with wireless, in hardy, but I got another automatic dist-upgrade from alpha5-6 using ethernet. Cupsys still seem to fail for the same reason. I have some kde programs, and unauthenticated packages, but in var/log/dist-upgrade/apt.log the packages seemed to be ones that depended on cupsys, not the reverse. I have a hardya6 alternate CD, and a copy of gutsy I'm building with a similar application load in an effort to try and solve the problem by elimination. I only have Windows at all, for the sake of a canon printer. The main system I use is still the pre upgrade Gutsy I had in a root tar file. I haven't been switching between systems too often, because I've been foldingathome,(I discovered that when I went looking for a solution to my clock or server failing.) and begrudge the hour or few getting nowhere.
I know here is a difference between kubuntu and ubuntu upgrades. but not how it would it affect automatic upgrades on xclient-script alternate or any other upgrades.
I'm spending too much space writing what I don't know. I'll update if I learn anything constructive.

I did an upgrade to kernel 2.6.24-12, the cupsys seems to have installed I used a an alternate Alpha6 Mar14 to supplement the download. I didn't check to see if the version changed There were other packages that still failed to load, but they are other bugs

Like Christer, I found this thread after experiencing the same problem updating CUPS after making the switch from apparmor to selinux.

[Xake (xake-rymdraket)]

The problem is SELinux, see bug 202983 for a better description (dpkg --configure tries to restart cupsd wich fails if cups is in enforce-mode due to SELinux protection).
Please fix.

Here is the real error:
