The beginning of an HTML editor

Posted on: October 24th, 2017 by

Kube recently gained a very basic HTML editor. It just does bold and cursive so far, but it’s a start for a more fully featured editor.

Of course you can also just continue to write plain-text mails if you prefer.

Enjoy =)

Support Kube through Kolab Now for fun and profit!

Posted on: October 23rd, 2017 by

If you ever wanted to try Kube a great way to do so is with a Kolab Now account. You will not only reap the benefits of using an secure, Switzerland hosted Open Source service, but you will also help sustain the development of Kube.

Kube now sports a sign-up link, allowing you to sign up directly from the setup page, which will result in a Kube Kolab Now account.

Use the link at the top of the page to get the reduced price offer.

The Kube Kolab Now account is special in that its feature set will follow the Kube feature set, and so will its price. So if you sign up now, for a more limited feature set, you not only benefit from a reduced price but also receive free upgrades in the future as we’re adding new features to Kube! You can still take advantage from the web interface from the beginning though, if you want to complement Kube with that.

Even if you are not sure if you want to take out a subscription, the 30 day trial allows you to test the service and get a full refund if you’re not satisfied.

So get Kube now and sign up for your account =)

If you contribute to Kube in some form, be that writing documentation, testing, filing bugs or somehow else helping Kube, your Kolab Now account just might be free ;-). Get in touch with me!

Kube flatpak, now slightly slimmer

Posted on: October 20th, 2017 by

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.

Incident Report: Backend Down

Posted on: October 17th, 2017 by

Earlier this morning, at 04:38 UTC, one out of the twenty-two IMAP backends in production stopped serving its mail spool, showing Input/Output errors on its disk. Our Standard Operating Procedure is to examine log files, flush vm caches, stop the virtual machine, and start it back up again. This occurred at 05:48 UTC. The IMAP backend in question did not come back up cleanly.

Junk Email Filter.com is Junk

We’re dropping our use of junkemailfilter.com “Spam DNS Lists”, because we have few positive experiences with it. Frankly, it is Junk.

Update on the Kube flatpak nvidia driver issue

Posted on: October 12th, 2017 by

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!

Announcing Service Windows: Implementing 2FA

Posted on: October 11th, 2017 by

As we recently announced, we have pursued an opt-in second factor authentication feature on Kolab Now. As described, the implementation is limiting users to the web client, and this requires some reconfiguration of various servers and services.

Kube flatpak not working with nvidia drivers

Posted on: October 11th, 2017 by

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.

Pushing Support to our Enterprise Customer Support Platform

Posted on: October 10th, 2017 by

We are preparing a transition from our current platform underpinning the support@kolabnow.com email address — based on OTRS — to a more up-to-date, feature-rich environment based on Phabricator.

For various reasons, we much anticipate this change. Not in the least we’ll have real-time notifications about new tickets, and user responses, and a few chat rooms — it’ll allow us to sort our workload better.
