On Ubuntu 17.10 installation hangs when installing ebtables package on the following:

Preparing to unpack .../ebtables_2.0.10.4-3.5ubuntu2_amd64.deb ...

update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults  

The output of ps:

root      4432  0.0  0.0   4592   840 pts/4    S+   10:37   0:00 /bin/sh /var/lib/dpkg/info/ebtables.postinst configure

Does it look like the script cannot complete?

How can I troubleshoot further?

Is it an alternate way to install an ebtables?

They overhauled the entire service booting method which means if you use 'old school' service control you get this weird message.

It's actually fairly simple, at least on Raspian; do this:

sudo systemctl start|stop <service>

There's other commands you can use too, but as you got this error message, presumably you followed an old blog post that said to type something like:

sudo update-rc.d <service> stop

and you got that error. The fix, for example, would be:

sudo systemctl stop isc-dhcp-server

Please see: https://lists.debian.org/debian-devel/2013/05/msg01109.html


None of this should affect anyone since in practice there will be no noticable difference other than the addition of a warning if the start or stop actions are used. I'm just bringing it up in case this will cause anyone problems--in which case shout now before it's changed!
