I have run dnf update again but returns with no change
SADLY, having said it all worked, when I did a Hard reboot…Nothing worked and I could not even get tot he log in screen…and not even the RESCUE option on the boot option screen worked…SO… Here I am , booted up from the USB, about to install again, for the 3rd time…
Hopefully it’ll work this time
This error is really serious (the others is about ABRT you can try reload it run the command indicate sudo systemctl daemon-reload) because it looks like your kernel get damage in someway than i don’t know. If you do see this error after you did reinstall again before you reboot try reinstall the kernel/s
sudo dnf reinstall kernel*
Try reinstall kernel before you do reboot if you can not repair the image of your kernel it will happen again. Maybe someone can help a bit more about how recover the kernel my first idea is just reinstall it before a reboot.
Edit: It also looks like that the kernel LTS than you did install present problems actually
