Hello friends. I installed fedora for the first time.
After installing fedora, I did the updates.
reboot after update. the first option in the grub loader gave this error.
Please boot into the working kernel. (5.17.5)
In a terminal can you check: sudo grubby --info=ALL
or sudo grep -r options /boot/loader/entries
and see if there is a difference in the args or options (they’re the same thing), between 5.17.5 and 5.18.18
If ro rootflags=subvol=root or a similar declaration is missing from 5.18.18:
Check and see if /etc/kernel/cmdline exists and is also missing that argument? sudo cat /etc/kernel/cmdline
If it does please:
remove the /etc/kernel/cmdline file sudo rm /etc/kernel/cmdline
and re-install the updated kernel sudo dnf remove kernel-core-5.18.18 sudo dnf upgrade
Thank you very much for your quick response and interest. The system crashed, I think I made a mistake. I am reformatting. if same problem occurs i will try what you said.
