Failed to start Remount Root and Kernel File system

Hello,

Following a power outage, my computer shut down completely.
When I turned it back on, I was greeted by a lovely black screen displaying the following messages:

Failed to start Remount Root and Kernel File system
Failed to mount /var/cache
Dependency failed for Local File Systems
Failed to mount /var/log
Dependency failed for Flush Journal to Persistant Storage
Dependency failed for Record System Boot/Shutdown in UTMP
You are in emergency mode

I use systemd and dracut.

Thank you for helping me.

I personally surrender at this point:

get live .iso, move everything you need to an external hdd. then re-install.

you could chroot and fix the /boot but an update interrupted causes some damage

2 cents

You could try to chroot into your system using this wiki.

Merci de vos conseils, mais j’ai contourné le problème en réinstallant totalement le système.
