Fedora 30 Grub Broken after hibernation with low battery

My grub stopped working after an hibernation, I tried to fix it but actually I did the oposite. After that I tried to use the boot-repair within a live usb Ubuntu, but it shows a message that “Please enable a repository containing the [grub2] packages in the software sources of Fedora 30 (mapper/fedora_localhost–live-root). Then try again.”

Here is my boot-repair log:
