openSUSE Conference 2018

This year openSUSE conference was held in Prague and, thanks to both my employer and openSUSE conference organizers, I've been able to spend almost a full day there.

I've headed to Prague with a Fleet Commander talk accepted and, as openSUSE Leap 15.0 was released Yesterday, also with the idea to show an unattended ("express") installation of the "as fresh as possible" Leap 15.0 happening on GNOME Boxes.

The conference was not so big, which helped to easy spot some old friends (Fridrich Strba, seriously? Meeting you after almost 7 years ... I have no words to describe my happiness on seeing you there!), some known faces (as Scott, with whom I just meet at conferences :-)) and also meet some people who either helped me a lot in the past (here I can mention the whole autoyast team who gave me some big support when I was writing down the autoinst.xml for libosinfo, which provides the support to do openSUSE's express installations via GNOME Boxes) or who have some interest in some of the work I've been doing (as Richard Brown who's a well-know figure around SUSE/openSUSE community, a GNOME Boxes user and also an enthusiastic supporter of our work done in libosiinfo/osinfo-db).

About the talks ...

I've re-shaped the very same Fleet Commander talk presented at FOSDEM'18 and also have prepared a demo to show the audience the magic happening on a CentOS 7.5 environment. In the audience we had around 20 people and the talk went considerably well considering that the demo just exploded. After leaving the conference room I took some time to debug what happened and seems that my master machine just hung at some point, thus the client machine wasn't able to download the desktop-profiles data from it (and it hung for so long that the DataProvider was marked as offline) and as I didn't have time to do a "live-debug" session I ended up proceeding with the rest of the talk (curiously, when writing this blog post I've logged in the client machine in order to debug the issue and the first thing that I see is the "pink background"!!!). We've even gotten a few questions! :-)
Sincerely, thanks to everyone who attended the talk!
I'm taking as an action item from this to write down a blog post on how to debug those issues (end-to-end) as, due to amount of components involved, something can go wrong on different parts, different projects and on.

By the end of my Fleet Commander talk, I've taken 5 minutes to say that I'm also a libosinfo maintainer (with a strong interest in the "tooling" part of the virtualization world :-)) and mention that during the trip from Brno to Prague I've crafted some patches adding support to openSUSE Leap 15.0 that was just released Yesterday and I'd like to show them an express installation performed via GNOME Boxes. In order to do so, I've booted the ISO, set up my username and password, clicked on "Create" and left my laptop in the presentation desk till the end of the next presenter's talk (who was Carlos Soriano presenting a nice "DevOps for GNOME with Flatpak" talk). By the end of Carlos' talk, I've just got back the mic and the screen and showed people that the installation have just worked. :-). The patches enabling this were submitted and hopefully we'll have them on both Fedora and openSUSE packages by Wednesday! :-)

So, summing up ... half of the demos worked, I've left both demos with action items (write a troubleshoot page and upstream the patches, which is already done) and I've met some really nice people in an equally nice environment!

Looking forward to attend next openSUSE Conference and thanks a lot for having me there!

Reporting Issues!

It's a recurrent thing on #sssd channel that people show up with different kind of questions, expecting straight forward answers about the problem they're having.

While I understand the expectations, it's not that easy for anyone there to help you without knowing context, without seeing logs, without seeing configuration files.

We (as SSSD team) have written down some documents that may help you and I sincerely would like to suggest people to take a look at those documents at the first thing. So, if you're having an issue, please, go through:

In our "User facing documentation" we have material about:

All of those should be useful to, at least, give us or meaningful information that we would be able to start helping you!

Also, keep in mind that we do not spend our entire day checking #sssd. We still have to fix the bugs we have, come up with new cool stuff and whatnot. It means that just dropping a message on #sssd may not be the best way to get a quick answer (although sometimes it may work!).

So, please, do not be afraid of file an issue on, following the instructions provided here. File the issue, provide us as much info as possible and drop us a ping on IRC in case we don't reply to your bug report quickly enough.

Last but not least, please, do not be this person:
21:27 -!- person [---] has joined #sssd
21:27 <person> Does there exist software worse than SSSD?
21:27 <person> I really don't think so
21:27 -!- person [---] has left #sssd []

Although I can understand how gratifying is to telling us how bad our software is (mind that I also do not think it's great), we'd like to hear from the user what makes it so bad and then, hopefully, be able to improve it somehow. But for doing this, we need meaningful bug reports, patience from our users to wait till the issue is fixed and to deal with us with some back and forth of testing packages and, mainly, understanding that we may have been busy with a bunch of different issues (which, please, does not mean that your issue is not important to us ... it is, we just need enough time to get to it!).

Fleet Commander!

A really short update!

I've presented a talk about Fleet Commander at DevConf CZ'2018, which basically show-cases the current status of the project after having the whole integration with FreeIPA and SSSD done!

Please, take a look at the presentation and slides.

While preparing this presentation we've found some issues on SSSD side, which already have some PRs opened: #495 and #497.

Also, fc-vagans project has been created to help people to easily test and develop for Fleet Commander.

Hopefully we'll be able to get the SSSD patches merged and backported to Fedora27. Meanwhile, I'd strongly recommend people to use the fc-vagans, as the patches are present there.

So, give it a try and, please, talk to us (#fleet-commander at!

And ... a similar talk will be given at FOSDEM'2018! Take a look at our DevRoom schedule and join us there!
