[pkg-dhcp-devel] Bug#793064: problem was in ddclient for me.

[Kenneth Johansson]

I had this exact problem.

I added
run_dhclient="false"
to /etc/default/ddclient

since I run ddclient in daemon mode it should not run from dhcpclient.

you have to set it to something else the
/etc/dhcp/dhclient-exit-hooks.d/ddclient
script fails.

or you could fix the problem in /etc/dhcp/dhclient-exit-hooks.d/ddclient
by changing
[ $run_dhclient = "true" ] || exit 0
to
[ "$run_dhclient" = "true" ] || exit 0
