I have an up to date F28 server that boots to the grub prompt. This
started after a failed dnf update.
The computer will boot to an emergency mode command prompt if I set it up
properly from the grub prompt.
grub> set root=(lvm/fedora-root)
grub> linuxefi (hd0,gpt2)/vmlinuz-0-rescue... root=/dev/mapper/fedora-root
grub>initrdefi (hd0,gpt2)/initramfs-0-rescue....img
grub>boot
I can get networking working
#ls /sys/call/net <- find Ethernet device is enp3s0
# ifup enp3s0
# ping
www.google.com
Now update it
# dnf update
Regenerate the grub2 config file
# grub2-mkconfig
Reboot
# shutdown -r now
It still boots to the grub prompt.
Why does it boot to the grub prompt and what do I need to do to fix it ?
