I installed pihole about a year ago, made some updates but now I can't access the web interface. I connected an hdmi cable to the raspberry and the monitor and searched for update for pihole. Updates get stuck installing FTL and I get this error: FTL...curl: (7) Couldn't connect to server Downloading and installing FTL Error: URL https://github.com/pi-hole/ftl/releases/latest/download/pihole-FTL-armv6-linux-gnueabihf not found.
In fact the link leads to a 404. The correct link should be:
How do I update if the link is wrong? Can I do it manually from command line?
By sending the pihole -d command I see that the IP address of my raspberry no longer exists. Why?
Thanks for your help!
Not having an IP seems like the source of all the issues observed. It's difficult to say how to fix it because it depends entirely on how it was set up before.
Make sure it's either cabled in with a working cable, or else that it is connected correctly to the WiFi.
Then run pihole -r and select Reconfigure and see if you are prompted to configure the networking. You mentioned it's a year old so this may still be the case for this installation. If so, you'll be able to repeat the correct settings for it to get its static IP address.
In otherwords, as long as you are connected to the network, you might be able to get away with using Pi-hole's own setup to configure/fix your networking.
