No login screen, unable to login on tty2 to tty6 with “Login Incorrect” error
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I'm getting this problem after my computer froze while updating. I use Fedora 28 KDE. I was shown in task bar that there 171 updates, so I clicked it, as it was updating the computer froze, so I pressed the reset button, since then I'm getting this problem.
I don't see any login screen, but I see a cursor over black screen, I can move this cursor. Hoping to login through command line, when I pressed CTRL+ALT+F2-F6, the text login, shows "Login Incorrect" when I type in my username and press "ENTER" to proceed to typing password. This problem exists across all Fedora entries on GRUB2 menu.
When I removed "rhgb" from one of the GRUB2 Fedora entries and started it, I was shown a real time log of the boot up process, in it I saw these, which I think might be the cause of this problem:
"ostree-system-generator failed with exit status 127"
and this error below it:
"Failed to start Security Auditing Service"

Seems like you got corrupted credential files, most probably /etc/passwd. Hopefully you may have a system backup that may help you to recover. This will require some investigation on what files got corrupted. I suggest you to boot in single user mode (addsingleto the end of your default fedora entry kernel command line). Once booted you will get a root prompt where you can remount your system as readonly (mount -o remount,ro /); then you can run fsck as the first step. This is not an answer, just some thoughts on how to start your system recovery.

Alternatively, if this is easy for you to remove your harddisk, you can use a USB/SATA adapter to use another system to run the fsck tool. Good luck

Thanks a lot Marcelo. You have no idea how appreciative I am for your helpful comments because I've been asking this question at two places officially related to Fedora, but till now I didn't get a reply there. Unfortunately I don't have any backup but I'll try that single user mode and see. BTW sorry I forgot to mention this, mine is an encrypted LVM, I tried mounting and running fsck through Kali which I have on the same hard disk, but because of encryption I had a lot of trouble accessing it, when I managed to get it running(which I'm not even sure I did correctly), the results were clean.

Instead of Kali (which is used for penetration testing), I recommend SystemRescuceCD on a USB stick to repair stuff.

I haven't yet tried the SystemRescueCD but in case it fsck shows clean, what can I do to repair the problem? Is there way I can remove the corrupted credential files and create ones?
