BeagleBone black: dnsmasq "is failed" (illegal cache-size=10000)

[arustictop]

Trying to install pi-hole on BeagleBone black (with Debian 9 stretch LXQt).

dnsmasq service fails to start with this error:
illegal repeated keyword at line 35 of /etc/dnsmasq.d/01-pihole.conf

This corresponds to line:
cache-size=10000

I don't understand what I can do to avoid this problem. I found threads about this, but not a satisfactory solution.

Any help is greatly appreciated

Actual Behaviour:

Are there any other dnsmasq configuration files? Check in /etc/dnsmasq.d/ and then also look for an /etc/dnsmasq.conf or /etc/dnsmasq/dnsmasq.conf. There is a second file out there with that same statement that was installed with the OS. It's also possible that NetworkManager is causing conflicts.

I found in /etc/dnsmasq.d/SoftAp0 this:

$ cat /etc/dnsmasq.d/SoftAp0 
interface=usb0
interface=usb1
port=53
dhcp-authoritative
domain-needed
bogus-priv
expand-hosts
cache-size=2048 

Which brings me to this solution:
https://discourse.pi-hole.net/t/pi-holes-default-cache-directive-conflicts-with-cache-size-directive-in-softap0/8369

And that appears to have done the trick after running pihole -r

Thanks!
