I issued a sudo dnf update --refresh and among I very long output I spotted this error.

  Running scriptlet: libvirt-daemon-5.6.0-5.fc31.x86_64              1391/1391 
  Running scriptlet: libwbclient-2:4.11.6-0.fc31.x86_64              1391/1391 
  Running scriptlet: kernel-core-5.5.7-200.fc31.x86_64               1391/1391

  Running scriptlet: abrt-dbus-2.14.0-1.fc31.x86_64                  1391/1391

Is there anything I need to urgently do before next reboot?
Thank you for a prompt reply

This is reported in RedHat Bugzilla, for Fedora and REDHAT against KERNEL:

https://bugzilla.redhat.com/show_bug.cgi?id=1625124
https://bugzilla.redhat.com/show_bug.cgi?id=1683128

Conclusion

sudo grub2-editenv create

Then for EFI

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

or for BIOS

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

And then attempt again to install your kernel or your update.

Nothing to do.
Complete!

(this is not important but I guess I have to redo the changes suggested here in my closed question about setting the default boot to windows, maybe related)

Now I’m going to reboot and mark this as solved if no issues arise… hope so :innocent: :wink:

Edit
Rebooted, all fine but I have to do again this activity.
I’ll mark as closed after that in a few minutes…

Sorry, I don’t understand what to do now…
this is what I see

[giuliohome@localhost ~]$ sudo cat /boot/grub2/grubenv
[sudo] password for giuliohome:

Looks strange to me…

Edit
I try with the following
sudo grub2-set-default 'Windows 7 (on /dev/sda2)'

  I'm sorry, didn't knew about this bug.  At least it's a bug :D
