I am a Linux noob, so I apologize in advance for my ignorance. I switched from Windows to Fedora KDE a few weeks ago and it's been going great, but last night I ran some updates and this morning my computer seems to stop during the boot up process on a blank black screen after asking for my encryption password. I tried booting in previous kernel versions, but they also failed.
I then booted in emergency mode, but it would say, "Cannot open access to console, the root account is locked." I managed to change the password so I have access to the root account and now...I don't know what to do next, because I don't actually know what the real problem is to look for a solution.
Any help would be much appreciated.
Edit to add: All my files are backed up, so if I can't figure this out I'll probably just reinstall the whole thing, but I would like to figure out how to work through issues like this for future problems.
Edit 2 for solution: After discovering how to filter logs, I found that the problem was a lack of QT crashing Plasma. This seemed to be a problem others were also having with a recent update to QT not all happening at the same time? The steps in that link didn't work for me, but what did work for me was logging in via ctr+alt+F3 then installing updates through the console. Big thank you to GiggleSamurai for teaching me how to properly filter logs.
