--- Failed Ubuntu Update ---

Start by using these commands (repeate and reorder as needed)
apt-get clean
apt-get autoclean
apt-get check
dpkg --configure -a
apt-get autoremove
apt-get update --fix-missing
apt-get -f install
If this fails with a particular package id'd. And to use a large hammer...
dpkg --remove --force-remove-reinstreq <package name>
Remove the packages very existance...
vi /var/lib/dpkg/status    
Find the block for the package and remove it. find / -mount -name <package name>* -print and remove those bits as well.  
ALSO CHECK THIS:
cat systemd-udevd.service
grep IPAddressDeny *
vi /lib/systemd/system/systemd-udevd.service


A new issue:
systemctl disable   winbind
mv /var/lib/dpkg/info/winbind.postinst  /var/lib/dpkg/info/00-winbind.postinst
