I found out if you remove the lxc folder, or probably at least unity8-lxc's folder, you can then correctly purge unity8-lxc. Hopefully a good workaround until this bug is patched...

Hi,

Thanks for entering this bug report. Looks like I didn't take into account that --purge will remove lxc/lxc1 first and remove lxc-destroy first before the unity8-lxc post-rm script is called which uses lxc-destroy.

Need to take care of this case.

for anyone reading this the lxc folder is on /var/lib and you need sudo so starting nautilus whit sudo will do the trick then go to /var/lib and remove the LXC folder
