Comment 2 for bug 448509

Thank you for this report, it is helpful.

I will review the apparmor profiles.

In the future, it is very helpful if the apparmor log is included, even better if you know the offending line.

Now this can be tricky as apparmor generates a lot of logs.

IMO it is best to work with one profile at a time and rather then disable it , place it in complain mode.

sudo aa-complain dhclient3

clear the log

sudo -c bash ">| /var/log/messages"

Then reboot and check the logs.
