Fedora 30 5.2.11-200.fc30.x86-64 was working smoothly.
An update download and install was suggested and I accepted.
And went to do some other things leaving the computer alone.
Apparently, version 5.3.6-200.fc30.x86_64 was installed.
When I came back I found a screen halted with the screen full of this log.
And this is the last screen of the boot log.
No matter the attempt, the process halts at some point.
The last instruction varies.
One more thing.
I can boot with the Fedora 12 version.
Very limited though, but it works.
Nautilus shows my HDD is intact with all of my data in it.
Only doubt I can have when version 5.2.11 update was taking place is if any of my cats stepped on the keyboard while I was away.
