Over the past weeks I’ve been busy improving our continous integration (CI) system for Kube. In particular, I’ve set up a Buildbot instance to build, test, benchmark and deliver Kube.

Kube flatpak, now slightly slimmer
While working on our flatpak build infrastructure I noticed that the flatpak is much larger than it should be. After quickly digging into the flatpak one of the culprits was quickly found; a bunch of unnecessary files such as include files were left.
Update on the Kube flatpak nvidia driver issue
After some investigation into the nvidia driver issue, the flatpak has now been rebuilt based on the org.freedesktop.Platform runtime.
A limitation of flatpak currently keeps flatpak from making the appropriate driver available from any other runtime.
As a nice side-effect the overall size of the flatpak has been reduced by removing some unnecessary parts.
If you have already installed Kube, please follow the following instructions to update to the latest version (in all other cases, install it now):
Update to the latest version (please note this will also automatically install the new runtime and driver extensions):
flatpak -y --user update com.kolabnow.kube
To remove the no longer relevant platform, run the following commands:
flatpak --user uninstall org.kolab.Sdk
flatpak --user uninstall org.kolab.Platform
To check if the relevant driver was installed you can use the following command:
flatpak --gl-drivers
If you have an nvidia card, this should give you a line similar to (depending on your nvidia driver):
nvidia-384-90
To run kube, use:
flatpak run com.kolabnow.kube
Please let us know in the comments if this resolves the issue for you, thanks!

Kube flatpak not working with nvidia drivers
It was recently pointed out that the Kube flatpak for Kolab Now does not work with nvidia drivers, leaving you with error messages like this:
libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast Unrecognized OpenGL version Unrecognized OpenGL version
As it turns out this is a problem with the extension system of flatpak that is used to provide the appropriate graphics driver to the application inside the container. It’s not quite clear what the best solution to the problem will be, but we’re working on it.

Journey to the Center of Kube: Sink
Kube is a client that allows you to work offline, so you can work no matter whether your train just entered a tunnel, you’re on board of a plane or you’re just too lazy to get up and ask for the free wifi password. One implication of this is that we have to deal with fair amounts of data.
Email tends to accumulate quickly, and it’s not uncommon to have mail folders that have somewhere between 40’000 and 200’000 emails in them, so we have to figure out a way to deal with that. At the core of Kube we therefore have Sink; the data-access and synchronization system.
