Title:
  Upgrade of procps disables net.ipv4.ip_forward=1

Status in procps package in Ubuntu:
  Confirmed

Bug description:
  Expected behavior:
  Settings in /etc/sysctl.conf won't be changed by an upgrade or there will be a prompt if the original file should be overwritten.

  What happened:
  After performing an upgrade of package procps IPv4Forwarding was disabled in /etc/sysctl.conf without asking:

  # Uncomment the next line to enable packet forwarding for IPv4
  #net.ipv4.ip_forward=1

  I was able to reproduce this behavior by using unattended-upgrades and
  also by upgrading manually (apt-get upgrade)

  My system:

  lsb_release -rd
  Description:    Ubuntu 18.04.2 LTS
  Release:        18.04

  apt-cache policy procps
  procps:
