Comment 25 for bug 1906331

To summarize:

1. Removing resolvconf looks like practical solution for people who face the problem

2. I do not know, whether crashes in such a case are natural and expected, or
    they simply trigger some buggy behaviour unlikely in „normal” situation.
   Depending on that either there should be some installation-level protection
  (like Conflict between packages) … or this is the way to reproduce.
