Avahi daemon installed?

[nzhome]

oh yeah, you were right mactr0n! you're tha man! I need more than what the homebridge installation wiki says. just libavahi-compat-libdnssd-dev is not enough.. I needed the full line that installs all the proper components. someone should update the homebridge installation wiki, no-where on the installation instructions does it mention this. Also I am probably the first one around here running Debian, I found the fix here: agnat/node_mdns#44 I also got homebridge to compile and run on Windows10 64bit Corei7.

HERE IS THE FIX:

sudo apt-get install avahi-daemon avahi-discover libnss-mdns libavahi-compat-libdnssd-dev

[zyanlu]

I'm getting this error because dbus-daemon is not running , and avahi-daemon is compiled without dbus, after recompile and restart the daemons , everything works fine.

besides,you could edit /etc/avahi/avahi-daemon.conf to see if avahi is compiled with dbus.

[server]
enable-dbus=yes  #default is yes, but if avahi is not compiled with dbus,this will trggier error.

I tried all the things here but unfortunately nothing helped me. I installed everything on Ubuntu 14.04 and it worked for some days. But suddenly home bridge didn't want to run anymore with the error:

[chymerix]

I'm getting the exact same error on Bash on Ubuntu on Windows 10 despite trying all the fixes. Does anyone have ideas for how to resolve this?

[Dirk23]

Still no fix on Ubuntu 14.04?? i am not on Windows with that error

[Dirk23]

i oversaw this now homebridge seems to run, because i uncommented the bus line!

[erhsch]

I had the same Problem:

*** WARNING *** The program 'nodejs' uses the Apple Bonjour compatibility layer of Avahi.

The homebridge is running but I can not pair my iphone with "Home" or "Eve". It is tried a few minutes and then canceled. Like a timeout. It does not matter how much the config file was changed.

My mistake was: I had installed after the installation of homebrige (here everything worked) pi-hole. This filters my DNS requests and blocks them.
As soon as this service was switched off, the coupling functioned again. Thus the homebridge must not be on servers with pi-hole, No Track or similar.
So I will install homebridge on another pi in the network.

Maybe someone has the same problem and I could help someone with it.

[teejay-87]

Got this problem too.
Running Debian Chroot on Synology Nas.

It worked fine till some months ago (I had time to check only now), then it suddenly stopped working.
I think this is ha something to do with a avahi-daemon update.
Something has changed with it because before I had this problem, the Synology interface was showing "avahi-daemon" as running, and now it states it is stopped, but I checked with ps and the result is:

root@DiskStation:/# ps -A | grep avahi
9611 ? 00:00:00 avahi-daemon

Anyone can help?

Also I checked the webpage linked in the errors homebridge prints at startup but they give you a 404.

[cusco]

I read somewhere that I needed to start the service dbus, and avahi-daemon
did and homebridge started fine:

[zesming]

I have the same error, and I have tried all the solutions above, unfortunately, it doesn't work for me. Then I just have tried to reconfigure all the environment, and found a way to fix the error.

This is my system info

If you installed homebridge with the README.md - Installation, and only run the command to install avahi.

sudo apt-get install libavahi-compat-libdnssd-dev

Just try to reinstall it.

sudo apt-get remove libavahi-compat-libdnssd-dev
sudo apt-get install libavahi-compat-libdnssd-dev

And comment the config line in /etc/avahi/avahi-daemon.conf because the apt-get command would autoinstall libdbus-1-dev, and it requires dbus lib.

[server]
#enable-dbus=yes # default is yes.

[davehun]

I get this error too when running without dbus and avahi-daemon.conf has:
enable-dbus=no

[thunderleo]

I start dbus，then avahi-daemon manually.
Go to work

[ixtli]

If you're here because you're trying to make this run on docker, it seems that this works:

FROM node:9.3

RUN apt-get -y update

RUN apt-get -y upgrade

RUN apt-get -y install avahi-daemon avahi-discover libnss-mdns

RUN apt-get -y install libavahi-compat-libdnssd-dev

RUN npm install -g --unsafe-perm homebridge

CMD service dbus start && service avahi-daemon start && homebridge
