Issue installing Collabora following official guide

I had also the connection error. Now its solved.
I have tried to made it with a new sub.domain with its own certificate from letsencrypt. No luck with this.
I found an red error in the log about my normal domain although lool was configured to other sub domain.
So I tried to change the settings to my normal sub domain (DynDNS).
Now I combined the Apache settings in the default-ssl.conf with all the other settings for my dyndns domain like nextcloud and others.
And … tata … it works.

I have solved one error in the docker as could be seen in /var/log/syslog:

docker[22800]: time="2016-07-22T17:15:20+01:00" level=error msg="containerd: notify OOM events" error="open memory.oom_control: no such file or directory"

By adding the following to /etc/default/grub:
GRUB_CMDLINE_LINUX="cgroup_enable=memory"

But when starting the docker I still get the following errors from the docker output itself:

So one small step closer but still so far away from the solution :disappointed:

You use Ubuntu 14.04?

Known problems:
This docker image does not work on Ubuntu 14.04 LTS, because Ubuntu 14.04 LTS has missing kernel compile option CONFIG_AUFS_XATTR=y, which is leading to setcap not working on docker’s aufs storage. Upstream bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1557776

So after messing around with AppArmor, SecComp and iptables for days, this hint also helped me with Ubuntu 16.04 Xenial, since Kernels before Ubuntu-4.4.0-22.38 on Xenial were also affected by the AUFS problem. I’m using Ksplice Uptrack to avoid reboots and was still running 4.4.0-21…

So for people running Xenial: make sure to have a current Kernel! Afterwards, I did not need to turn off AppArmor or do anything else besides what is described in the official guide.

Thanks for that tip @accolon. I was running Debian 8.5 and couldn’t get it to work. I then created a new VM running Ubuntu 16.04 Xenial (running kernel 4.4.0-31-generic). Done the same installation steps as I did before and now Collabora is working.

Guess sometimes you do have to get the correct OS to get something working.

There is one thing that isn’t working normally, the menu top left is not showing when clicking on ‘Office’, only when clicking on the logo it goes to the main page. I will open a new topic for it

I also had the issue about symlinking etc, i resolved it updating to kernel 4.6 (debian jessie).
Now I have an other problem:

Upgrading my kernel (from 3.16 to 4.6) also fixed it for me (Debian 8.5)

I found that libreoffice online asks wopi urls adding “?encoding=text” to the url.
This ofcourse invalidate the token (the original url is https://cloud…etc/etc/etc?access_token=), so I manually fixed richdocuments app code using a $token = str_replace("?encoding=text", “”, $token);… Now it works :smiley:

I moved my temp VM (which was working with Collabora) to my main domain, but now it fails again. From the docker output I get the following error:

Hi,

How do you do to upgrade to kernel 4.16? I try this but the kernel I installed doesn’t work with docker :frowning: May be I don’t foudn the good kernel

I’m running the docker image on ubuntu 16.04 with the latest kernel. I’m getting the same error and my logs shows the following before the connection is refused

Jul 25 11:36:53 lenz systemd[1]: Unit docker.service entered failed state.

I am running docker 1.11.2-0~jessie

EDIT: I was able to get it to run again by running rm -rf /var/lib/docker/aufs and then start the docker service again

So after upgrading the kernel under Debian to 4.6 I am still stuck on the same step as before:

It is unclear to me why it states “App is not enabled”. When I check the URL in the first line manually I do get the following output:

{"BaseFileName":"New Spreadsheet.ods","Size":7130,"Version":"0"}

Does the “HttpOnly” element have any influence on it, since all communication is done via HTTPS?

After upgrading to kernel 4.6 i also changed the docker storage driver (from aufs to overlay).
And remember that if you change it you will lose al the images you have built.

I’m just wondering does the server have to be running on the same host as the client even if it’s on a different subdomain?

After upgrading to 4.6.0 and change the docker storage to overlay, it takes more time to show the error, but it end with it…

This is the logs:

Regarding the connection error: Seems that the root cause is simple:


Turns out that the browser wants to connect to localhost.
In other words: This might work in the case browser and docker container run on the same box.

@rainer this looks like you probably haven’t configured your external URL in the admin area of your NC installation.

Eventually, I got it running :slight_smile:

What I did: started the container with
docker run -t -d -p 127.0.0.1:9980:9980 -e "domain=cloud\.example\.com" --restart always --cap-add MKNOD collabora/code
In the Collabora configuration in Nextcloud, URL to Collabora Online server is https://cloud.example.com/ (thanks, @jurgenhaas!
I think that’s all.
No need for additional certificates, the installation guide is wrong here.
Of course, you need to replace cloud.example.com with the name of your own nextcloud server.
OS: OpenSUSE 13.2
