[SOLVED] Pihole + Network Manager configuration

[deHakkelaar]

Solution is in this post by @DL6ER:

Problem with FTL and dnsmasq after pihole -up (Ubuntu 16.04.5 LTS)

In your /etc/init.d/pihole-FTL you can find a line su -s /bin/sh -c "/usr/bin/pihole-FTL" "$FTLUSER" replace it by /usr/bin/pihole-FTL

Edit the file as proposed with for example nano:

sudo nano /etc/init.d/pihole-FTL
