And to answer your question, no, I didn't alter resolvconf behavior when running 14.04. When forcing a "dpkg --configure -a", and then a "apt-get -f install", it seems to fix that problem and I have a properly running system.
I tried to upgrade another computer from 15.10 and didn't encounter that problem, I got systemd upgrade error BTW, but it was fixed by the automatic "dpkg --configure -a" run at the end. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to resolvconf in Ubuntu. https://bugs.launchpad.net/bugs/1536335 Title: package resolvconf 1.78ubuntu1 failed to install/upgrade: le sous- processus script post-installation installé a retourné une erreur de sortie d'état 1 Status in resolvconf package in Ubuntu: New Bug description: Upgrading from 14.04LTS to 16.04LTS (Xenial), I got this upgrade error.
