These solutions all relay on the system booting. But what do you do if your system is not booting because of samba?
If you are stuck in recovery mode, IE the rescue disk. apt-get does not always work, in fact it will get you a seg fault in a recovery shell, atleast on Ubuntu from what I've seen. To get around that, you can use
dpkg --purge --force-all samba and also for common and winbind if the system still wont boot.
Remember if you are in the recorvery mode shell, do not use sudo, because that will cause a seg fault. Just use the commands as you would if you were in as root.
But I have had Samba cause a system to stop booting, and this is how I was able to rip samba out, and then do a clean install after I got the system booting all the way up again. Once it's booted all the way up, go through and do the
sudo apt-get remove --purge samba samba-common command to make sure everything has been removed. Unfortunately, you may also have to manually delete some items, because dpkg does not always delete startup scripts and other items the binary creates. This is what I've had to do, to thoroughly remove samba, when I couldn't get the system to boot.
I hope this helps someone who was stuck in the same situation as me.
