Pihole says it is running but cannot get in to admin or block site in terminal

Help Community Help

The issue I am facing is that I am unsure if pi hoile is working. I can't login to the admin web interface, when I type in https://192.168.y.x/admin or https://192.168.1.x:80/admin or http://pi.hole/admin i get "page not found" page. When I try and do a pihole -b sitex it says added to block list but I can still visit the site.

Details about my system:
This is a fresh new install of Ubuntu Server 20.04 LTS with the kde-plasma gui on top nothing else was installed. This is my 3rd time reinstalling Ubuntu Server 20.04 LTS the first time I installed nextcloud and it was hosted at my root ip.

The PC is a lenovo m73 thinkcentre i3 4gen with 8gb of ram.

What I have changed since installing Pi-hole:
on my second install I made my ip for this system a fix ip on my route.

Ubuntu 20.04 is not an officially supported OS
https://docs.pi-hole.net/main/prerequisites/

Ok, you got serveral different issues:

  1. Lighttpd (webserver is not running) -> no web Gui
    What's the output of:
 sudo service lighttpd status

cat /var/log/lighttpd/error.log
  1. FTL is not running because it can't access the databases. -> no DNS resolution
ls -lha /etc/pihole/

Im not sure what this means

and i'm guess reinstalling wont fix this i even installed a pihole on a docker and still nothing.

"Ubuntu 20.04 is not an officially supported OS"
I see,
what can one do I guess while waiting for a patch or updates to include Ubuntu 20.04.

8

Ok, lighttpd seems to miss a dependency

sudo apt install gamin

and then

sudo service lighttpd restart

Add

This needs sudo powers
sudo cat /var/log/lighttpd/error.log

9

this is what I get when i follow the instructions.

:/$ sudo apt install gamin
Reading package lists... Done
Building dependency tree
Reading state information... Done
gamin is already the newest version (0.1.10-6).

:/$ sudo service lighttpd restart
:/$ sudo cat /var/log/lighttpd/error.log
cat: /var/log/lighttpd/error.log: No such file or directory
:/$

10

then i run systemctil status lighttpd command again

sudo systemctl status lighttpd

Strange that it was already installed.
What's the output of

ls -la /var/log/lighttpd

12

I tried doing it in docker and still dosn't work. are there any members you know that successfully got it working using ubnutu server.

14

I don't know if anyone was successful, but you can search the forum for docker and ubuntu 20.04

15

So there isn't anything i can do at this time. and do you know if they work on updating pihole to work on updated os or is this a ubuntu issue.

16

I'm not a pihole developer - I can't tell you what they work on. I've seen this:

But no feature request was ever created to support 20.04. so far. Maybe you want to open one?

17

I see that pralor commented link to this chat/ thread.

18

Pralor is a bot, linking discourse with github.

19

lol ok im dumb, thank you for taking the time to help me i guess its a waiting game.

20

so it said to go to the discourse to make a request, but I'm unable to. My guess is that I'm new and need more rep to open up a new request for Ubuntu 20.04 support.
