This is fixed in pptpd 1.4.0-9 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=829418
I just downloaded 1.4.0-10 from the yakkety repo at http://packages.ubuntu.com/yakkety/amd64/pptpd/download and installed it using dpkg. Once the xenial repo is updated this issue will be resolved. ** Bug watch added: Debian Bug tracker #829418 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=829418 ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: Confirmed => Fix Released ** Also affects: pptpd (Ubuntu) Importance: Undecided Status: New ** Changed in: pptpd (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615916 Title: Ubuntu upgrade failed 14.04 -> 16.04 (pptpd) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pptpd/+bug/1615916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
