I'm not exactly sure what the problem is here, but autoremove should never break :-)

Could you please show the contents of /var/log/upstart/lxc-net.log?

[Tycho Andersen (tycho-s)]

Hey, sorry about that, forgot to post:

CloudFive:~/packages/cloud-installer/tools 1$ sudo cat /var/log/upstart/lxc-net.log
iptables: Bad rule (does a matching rule exist in that chain?).

[Stéphane Graber (stgraber)]

What kernel are you running on?

The last time I saw that specific error, it was with a kernel not supporting mangle+fill-checksum.

CloudFive:~/packages/cloud-installer/tools$ uname -r
3.13.0-5-generic

Basically, a reasonably recent version of the stock trusty kernel. Is
there somewhere I can look specifically?

Do you happen to have ufw installed? Did you manually edit your
firewall at any point since the last boot before that failure?

In any case, it seems best to add '|| true' to the end of all the
iptables commands in the post-stop.

[JoaoCC (joaocc)]

I have this same problem.
Ubuntu 14.04, lxc 1.0.3-0ubuntu3, shorewall 4.5.21.6-1
Basically "lxcbr0" doesn't start, and I get the following message at /var/log/upstart/lxc-net.log
    iptables: Bad rule (does a matching rule exist in that chain?).
Any ideas?
Thx

Please open a new bug

On ubuntu 14.04, to remove lxc, first run:
service lxc-net stop
then
aptitude remove lxc
