Hi,
I have this critical problem with Fedora (F22, F23, F24 and F25):
https://bugzilla.redhat.com/show_bug.cgi?id=1227736
I get a minimal grub each time there is a kernel update and the updates
are done with gnome-software. When that happens, I need to boot from a
live DVD and reinstall grub.
`dnf upgrade` works fine.
It happens on different hardware, and it doesn't happen only to me.
I would be happy to provide more information in bugzilla, but nobody
replied since a long time.
Thanks,
Sébastien
