Anyone using the network-manager-pptp package, the lastest du, is asking to remove it.
this is what my d-u looks like;
The following packages will be REMOVED:
network-manager-pptp network-manager-pptp-gnome
The following NEW packages will be installed:
linux-headers-3.14-1.towo-siduction-amd64
linux-image-3.14-1.towo-siduction-amd64
The following packages have been kept back:
lightdm-gtk-greeter
The following packages will be upgraded:

libglibmm-2.4-1c2a libgtkmm-3.0-1 libijs-0.35 libjim0.74 libmikmod3
libmtp-common libmtp-runtime libmtp9 libparted0debian1
linux-headers-siduction-amd64 linux-image-siduction-amd64 openssh-client
openssh-server openssh-sftp-server parted patch ppp pywwetha sidu-base

that being said the offending package is ppp, if you want just
apt-mark hold ppp
then d-u and then unmark ppp as a work around and wait.
