journalctl log of problem

Opening a Hotspot in Gnome does not work, the dnsmasq fails to start. I
attached the log from journalctl. Important info is 

12:43:31 mybox dnsmasq[12028]: cannot open or create lease file
/var/lib/NetworkManager/dnsmasq-wlan0.leases: Permission denied
12:43:31 mybox dnsmasq[12028]: FAILED to start up

Result is that devices can connect to the hotspot, but do not receive an IP
address (Android is stuck in "obtaining IP address" step)


I could fix this with a change to apparmor profile:

--- /etc/apparmor.d/usr.sbin.dnsmasq~    2018-10-22 11:53:18.000000000 +0200
+++ /etc/apparmor.d/usr.sbin.dnsmasq    2018-11-05 13:09:25.033720448 +0100
