[Bug 358035] [NEW] can't create file: permission denied by apparmor

[OlaJi]

Public bug reported:

Upgraded from Ubuntu 8.10 to 9.04 and lost all network connections.
Found out that it was it was a problem with dhcp3-client. See syslog
list:

When I disabled the apparmor profile /sbin/dhclient3 the network
connection with NetworkManager works again. I don't know if this is a
bug in dhcp3 or apparmor, but its a bug that breaks the system. It's
hard to get back on track without a network connection...
