I am on Fedora 28 and thought I upgraded to 31, but I noticed during boot, it still shows Fedora 28.

So, it seems like the upgrade did not finish. I see that the grub config has not been updated.

So, there is this bug https://fedoraproject.org/wiki/Commo...ter_an_upgrade

When I try to run

grub2-install /dev/sda

I get

grub-install: warning: file system `ext2' doesn't support embedding.


How can I fix this?

What do you get from: parted /dev/sda print

And "lsblk -f"

Is your F28 installed in 32bit or 64bit?
F31 does not support 32bit and will not install/update on any 32 bit installations.
If you are running the 32 bit version then the only upgrade path will be a complete reinstall as 64 bit.

Maybe run to update the grub menu.

https://unix.stackexchange.com/quest...ystem-isnt-emb would make me think you tried to install to partition instead of mbr but your command says disk. Could it be that you booted to a usb media to try this command?
