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
