PiHole 4.0 Update
I know this is not about Wi-Fi but it is something I recently ran into. I am using a PiHole as my DNS server at home. However, during the most recent upgrade to 4.0 the FTL failed to upgrade properly. After running, "pihole -up" I received, [✗] Backing up index.lighttpd.html No default index.lighttpd.html file found… not backing up … [✗] Downloading and Installing FTL Error: Unable to get latest release location from GitHub The solution is here: Type on your PiHole: sudo nano /etc/resolv.conf Change the name server from 127.0.0.1 to 8.8.8.8 for googles DNS server. Save and quit the document. Then again run: pihole -up This will allow your pihole to reach Github and update the new FTL.
