[Bug 408779] [NEW] [karmic] dhcp fails with wireless link under 2.6.31-5-generic #24

[Carey Underwood]

Public bug reported:

My wireless adapter fails to connect after applying updates this
morning.  Network manager associates with the network correctly, but
fails to receive an ip address.  Investigating from the terminal, I can
manually assign a network address and then connect to the network, but
running "sudo dhclient wlan0" fails with an error:

Open a socket for LPF: Operation not permitted.

Disabling apparmor via "sudo /etc/init.d/apparmor stop" makes things
work properly again.
