Using spreed-webrtc on Raspbian (Raspberry 3)

I’m trying to install the spreed-webrtc plugin on Raspbian but I can only find the Ubuntu package. Is there any easy way to install spreed-webrtc on Raspbian or maybe detailed install/build How-Tos which can help me to set up spreed-webrtc properly? I managed to build the spreed-webrtc Server but now I don’t know how to set up the nginx Server, how to autostart the spreed-webrtc and how to set up a letsencrypt certificate with renewal cron job. I’d really appreciate if someone could write a tutorial or create a package.



we have a ppa for Ubuntu at but as of now it does not contain armhf or arm64 packages. You could rebuild that package for armhf by following instructions like here. I will check what needs to be done to get armhf and arm64 packages on Launchpad.


Regarding the configuration for Nginx we have an example Nginx configuration in the repository.

And last the letsencrypt is more or less unrelated to Spreed WebRTC or Nextcloud but i suggest you look into which has all you need. There are some PPAs for this tool out there as well.


Thank you for the quick reply. I’d really appreciate a Raspberry ppa because at the moment the build and setup process is not easy and probably stops many nextcloud users from installing spreed-webrtc on Raspberry Pis or other arm devices…

I’d like to see a armh build too; for odroid xu4

The development PPA for Spreed Webrtc at now has armhf packages for Ubuntu 14.04 and 16.04.

sudo apt-add-repository ppa:strukturag/spreed-webrtc-unstable
sudo apt-get update && sudo apt-get install spreed-webrtc

Please let me know how it goes.

Thank you! Will try it and report here. :slight_smile:

Unfortunately I didn’t manage to install it on Raspbian (error: could not find a distribution template for Raspbian/Jessie). Maybe you can add it to the supported distros?

I also tried to download the debs directly and to install them with the package manager without success.

Thank you!

Installation under Ubuntu 14.04 LTS on odroid xu4 works…
The server is up, but if I call it through nextcloud or throu /webrtc/ it first shows the spreed logo and than “Failed to load app!”

I’ll have a look on it later on or at the weekend…

Now it works! :slight_smile:

Well, launchpad is an Ubuntu tool and thus does not make it possible to provide repositories for other distributions than Ubuntu. But it should work when you download the package directly assuming your Raspbian is mostly compatible with Ubuntu 14.04. Could you post the full output so we can see what happens when you dpkg -i the package on Raspbian.

Yes, thanks for confirming :thumbsup:

I installed golang-spreed-webrtc-dev_0.27.1-1~trusty2_all.deb first (sudo dpkg -i and then sudo apt-get -f install for dependencies). Then I installed spreed-webrtc-assets_0.27.1-1~trusty2_all.deb and spreed-webrtc-bin_0.27.1-1~trusty2_armhf.deb without any errors (both with sudo dpkg -i). At least I tried to install spreed-webrtc_0.27.1-1~trusty2_all.deb (sudo dpkg -i) and got this error:

Mhm that looks strange. From looking at the postinst script i fail to see how this could exit with 102. Could you please try to run the postinst script manually and post the output please.

sudo /var/lib/dpkg/info/spreed-webrtc.postinst configure

Thanks for your help!

To whom it my interest…
…update to 0.27.1-2 on ordoid xu4 from the repository ppa:strukturag/spreed-webrtc-unstable worked without problems…

Any update on running spreed-webrtc on Raspian?
