[volkswagner]

Describe the Bug

coolwsd crashes and restarts every time when opening an office document

Steps to Reproduce

1. open any office document via web browser

Expected Behavior

File should open in edit mode and be ready to edit.

Actual Behavior

File opens in edit mode, after ~5 seconds warning appears "The server has been disconnected". Wait another 10-30 seconds and file is now editable.

Seeing the same problem on my side as well.
Running Collabora via Kubernetes Helm chart and linked it with a Nextcloud instance

As soon as I want to edit an existing file a pod crashes after a couple of seconds and gets recreated.

Using previous version (24.04.13.1.1) fixed this bug.

[volkswagner]

How can I get an earlier .deb package 24.04.13.1.1?

[derritter88]

How do you run Collabora?
Docker/Kubernetes or on bare metal/VM?

[volkswagner]

I'm running Collabora in a dedicated VM which also runs NextCloud installed from .tar file.

[derritter88]

Okay you can try to find a previous version at the repository you are using for Collabora and install it manually.
Then you pin this package so it does not get updated via apt upgrade for the moment.

[volkswagner]

It looks like they only publish the latest release https://www.collaboraoffice.com/repos/CollaboraOnline/CODE-deb/

I saw in the repo debian folder there's mention of a newer version 25.0. I tried modifying my debian to unstable/sid
to see if I can get to a later version, but moving to sid still shows:
coolwsd is already the newest version (24.04.13.2-1)

[derritter88]

Have you also tried apt list -a <package name>

[volkswagner]

Yes, it only shows the broken version with various architectures.

root@cloud:/etc/apt# apt list -a coolwsd
Listing... Done
coolwsd/unknown,now 24.04.13.2-1 amd64 [installed]
coolwsd/unknown 24.04.13.2-1 arm64
coolwsd/unknown 24.04.13.2-1 ppc64el

I tried older URLs for the repo and they all seem to redirect/show current version only.
https://www.collaboraoffice.com/repos/CollaboraOnline/CODE-debian10

[derritter88]

Unfortunately I do not know where you could find the previous package version.
You could try to run it on a local Docker/Podman as there you could use the previous version.

[timar]

Hopefully it is fixed by 7071c1e
The stack trace looks similar.
The next CODE 24.04.13.3. will have the fix.

[derritter88]

Szia @timar ,

fingers crossed - I would be happy to test it if you push it on the container repository.
