[feisty] avahi-daemon 0.6.17 fail on boot

I now be able to mount the usb + cdrom device, I had a bad configuration of pam modules, sorry for this notification.

The avahi-daemon still has a problmes, this problem was notified here:

I'm not be able to discover hosts running on my network.

You have apparmor installed?

I have the same problem with avahi-daemon and uninstalling apparmor the problem disapear.

I have the same problem.

I have a WiFi USB adapter and if I configure the WiFi network in /etc/network/interfaces, avahi-daemon fails on boot.

This is my /etc/network/interfaces file:

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp
name zd1201
wireless_channel 3
wireless_mode managed
wireless_essid THOMSON
wireless_key [MY WEP KEY]
address 192.168.0.11
netmask 255.255.255.0
gateway 192.168.0.1

One solution is not configure in /etc/network/interfaces, and when GNOME starts, configure manually the WiFi using Network Manager, but this method is ugly.

I don't know why there isn't a solution.

Please don't assign bugs to ubuntu-core-dev.

I see this with apparmor installed too, I will try to investigate it further.

Ah-ha! I've tracked this down. The issue is with how the Feisty AppArmor replaces the "capability" module. If the "apparmor" module hasn't been built, "capability" can't load, meaning Avahi doesn't have what it needs to do its work.

So, the solutions are either:
1) run Gutsy (where this is fixed)
2) get the apparmor-modules built and install (see below)
3) uninstall AppArmor (which removes the /etc/modprobe.d/apparmor file)

Here's how to get your apparmor module installed again, after a kernel upgrade:

 sudo apt-get install apparmor-modules-source
 sudo m-a -v -t prepare
 sudo m-a -v -t -f build apparmor-modules
 sudo m-a -v -t install apparmor-modules
 modprobe apparmor
