Systemd v230 is in backports and it breaks everything with its stoopid interface names. Ian Murdock Edition users now need to:
sudo apt-mark hold systemd
sudo apt-mark hold udev
sudo apt-mark hold systemd-sysv
sudo apt-mark hold xrdp
sudo apt-mark hold audacious
sudo apt update
sudo apt upgrade

No change for users of the 9-11 edition:
sudo apt-mark hold locales
sudo apt update
sudo apt upgrade
