I am currently using a Fedora 27 desktop, and I was trying to update it to Fedora 29 today. During the updating, I turned off my machine accidentally, and now I could not start my machine. I got this screen, and I am not sure
Try booting into rescue mode, then run:
systemctl start NetworkManagerto make sure the network is up.
dnf remove duplicates
Then try rebooting again.
If you can’t even get into rescue mode, or dnf is broken, you might be a bit stuck…
I tried this but still got stuck, I just installed Fedora 29 from scratch.
Whelp, at least you got it working I guess?
