Had done a "pihole -up" to Pi-hole Version v3.3 Web Interface Version v3.3 FTL Version v3.0
[i] Installing configs from /etc/.pihole...
[i] Existing dnsmasq.conf found... it is not a Pi-hole file, leaving alone!

[i] Creating log and changing owner to dnsmasq... log already exists!
[✗] Backing up index.lighttpd.html

ended with line: Unable to complete update, please contact Pi-hole Support

I am not sure why directly after the upgrade it didn´t work. Again, I am by far a Linux expert, but one of the big failures obviously was to copy /etc/dnsmasq.d/01-pihole.log to /etc/dnsmasq.conf.
That kept dnsmasq.service start failing allover again. I then emptied the /etc/dnsmasq.conf (basically removed all entries as they would exist in 01-pihole.conf) and then the command pihole restartdnsdid succeeded.
