i removed apparmor apparmor-utils packages and it works ok!

[Jamie Strandboge (jdstrand)]

Can you please post the contents of your /var/log/kern.log when you were having the problem? Please see https://wiki.ubuntu.com/DebuggingApparmor for details.

I highly recommend you reinstall apparmor-utils otherwise all apparmor protected programs are no longer protected. A better alternative is to leave apparmor enabled and put the profile in complain mode. See the above link for details.

[Jamie Strandboge (jdstrand)]

Actually, just removing apparmor-utils should not prevent apparmor from protecting applications, but it also shouldn't have helped your problem. Please make sure you have the following installed when reporting back with the problem:
apparmor
apparmor-utils
libapparmor-perl
libapparmor1

Simply doing 'apt-get install apparmor apparmor-utils' should give you everything you need.

i run sudo aa-complain /sbin/dhclient and it works in this mode.

Thanks for your response. Can you update /etc/apparmor.d/sbin.dhclient3 to have in it's '/sbin/dhclient3' section:
  network udp,

Then do:
sudo /etc/init.d/apparmor force-reload

and report back if that works for you?

[Sebastian Martinez (tychocity)]

after today updates including dhcp3-client dhcp3-common the dhcp work ok.

[Jamie Strandboge (jdstrand)]

For clarity, you did NOT add 'network udp,' as suggested and today's update fixed it for you?

[Sebastian Martinez (tychocity)]

no
