Discover crashed before completion. Subsequently, I was unable to reboot my sytem using the plasma desktop menu. I had to use sudo reboot in the terminal. -- Backtrace (Reduced): #6 0x00007f66f191b428 in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:54 #7 0x00007f66f191d02a in __GI_abort () at abort.c:89 #8 0x00007f66f23cff41 in qt_message_fatal (context=..., message=<synthetic pointer>) at global/qlogging.cpp:1648 #9 QMessageLogger::fatal (this=this@entry=0x7ffc2385b570, msg=msg@entry=0x7f66f4c24322 "%s") at global/qlogging.cpp:790 #10 0x00007f66f4a91fe3 in QSGRenderLoop::handleContextCreationFailure (this=this@entry=0x1df0690, window=0x1ddb020, isEs=isEs@entry=false) at scenegraph/qsgrenderloop.cpp:262 1721354 3 aleixpol 2018-01-10 17:51:42 +0000 *** This bug has been marked as a duplicate of bug 375913 *** 1722378 4 fsandefur 2018-01-15 19:19:11 +0000 Definitely NOT solved.

My noting this as Compiled from Sources was an error on my part. I have installed everything from Either a dl'd DVD or repositories. I apologise for not noticing that until you asked. However, when the application crashed at a point the ongoing updates remain unfinished, leaves behind broken packages, and locks up my system before completing the boot up, I call that unbootable. I had to use grub to return to a previous configuration, drop to root, and use apt-get and dkpg to repair or complete the upgrades to be able to use my system. 1722747 7 cfeck 2018-01-16 23:19:42 +0000 Frank, please read bug 375913 comment #2.
