 I have installed Fedora on my computer 3 or 4 years ago. Since this installation, I have installed many packages and upgraded it every 6 months. Unfortunately, Gnome Software has never worked for me, and I never took the time to debug it. Like many people, I am using the old method with `dnf-system-upgrade`, which worked pretty well. But this time, I had a segfault on dnf during the offline upgrade. The only information I got was the following lines:
 
-```raw
-kernel: show_signal_msg: 7 callbacks suppressed
+<pre style="white-space: pre"

+</pre>
 
 Just after the segfault, my computer rebooted on Fedora 26.
