Package: network-manager-pptp
Version: 1.2.4-5+b1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?

I did a normal apt upgrade which updated network-manager-pptp,
network-manager, ppp, and pptp-linux to the latest testing versions as of
24Feb2018. This caused my PPTP vpn connection to fail to connect because of
authentication issues with the MSCHAP and MSCHAPv2 protocals.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Downgrading just pptp-linux was not effective so I also downgraded the
following packages as well to get ppp to version 2.7.4-1+4:
gir1.2-nma-1.0 libnma0 network-manager network-manager-gnome
network-manager-pptp network-manager-pptp-gnome ppp pptp-linux pptpd

   * What was the outcome of this action?

After downgrading the packages, The PPTP base vpn connection is working.

   * What outcome did you expect instead?

I would have expected that the upgrade would not have broken MSCHAP and
MSCHAPv2 authenthication.
