Yast2 Modules Not Loading in OpenSUSE Leap

I finally upgraded my system from 13.2 to Leap 42.1. There were a few problems along the way, but overall it was a smooth upgrade. I remembered to remove the nVidia drivers, but forgot to disable the nVidia repository so it installed a driver that no longer supports my trusty 8600GT. After figuring that out, networking wasn't working but just needed quickly reconfigured, same for sound. But the one thing that was stumping me was yast2 failing to load any module in GUI mode. No matter which I loaded, I would get the error:



Run command: /sbin/yast2 sound &
terminate called after throwing an instance of 'YUIPluginException'
 what():  Couldn't load plug-in qt
YaST got signal 6 at file /usr/share/YaST2/modules/Wizard.rb:782
 sender PID: 3605
/sbin/yast2: line 440:  3605 Aborted                 $ybindir/y2base $module "$@" "$SELECTED_GUI" $Y2_GEOMETRY $Y2


A quick visit to Google resulted in multiple posts stating that yast2-gtk was needed but isn't getting installed. I use KDE but let's give that a try. zypper in yast2-gtk and nothing changes. So let's try zypper in yast2-qt. This results in libyui-qt6 providing yast2-qt is already installed. I forget why now, but I did a rpm -qa | grep libyui and saw libyui6, libyui-qt-pkg6, etc. So logic would dictate at this point I need libyui-qt7 as well, so I installed that and bingo, it installed a couple of libraries and the sound module now loads. Software management started to load, but then threw up an error that qt-pkg could not be loaded. So zypper in libyui-qt-pkg7 (another package that I had the corresponding version 6 of I overlooked the first time) and I appear to be back in business.

Hope this helps someone. There's a lot of posts stating you need newer version of one package or another, but none that really specify exactly what to install.

AlwaysOn Availability Groups and User Accounts

I recently built a AlwaysOn Availablity Group for my companies database server on SQL Server 2012. With three databases for mission critical applications running on the database server, we needed a little more protection than a weekly backup that we can restore.  So I took two fresh servers, installed Windows Server 2012 Standard and SQL Server 2012 Enterprise on each and found this link, which is a great place to start when building an AlwaysOn Availability group.  There's a couple points that were either missing or noted so briefly that I missed them, but it pretty much covers everything from end to end.  There's also an ebook called "High Availability Solutions" downloadable from Microsoft with a lot more information and detail.

Exchange Server component Mailbox role: Mailbox service failed.

The short version of this story is READ THE LOGS!  Now here's the long version.

I was trying to install Exchange 2013 in my lab environment and kept running into this error consistently. I scoured the Internet and tried everything that was suggested for anything even similar, with no success. At one point I even scrapped the VM and built a new Server 2012R2 VM from scratch, and the same thing happened. The Exchange setup wizard would fail at about 97% into the Mailbox role installation with the following output. It's not all here, because its ultimately wasn't of much use.
