Obviously I don't know your setup, but it's more normal for
the bootloader to be installed at device level rather than at
partition level, so you would want:
grub2-install /dev/sda
Obviously this should have been fixed as part of the upgrade
process - that's why the page is called "common bugs" because
it's a bug.

This seems like a pretty major bug in some component somewhere. I
don't
think this is a recoverable bug for most people, meaning they would
have
to reinstall and possibly lose everything.
What component is at fault? I'd like to report this bug and have it
fixed
asap before other people experience a non-working system after
upgrade.
No idea how to recover the system at this point. It does have valuable
work related code and docs on it.

Thanks. It's nice that there is a writeup. But are non-technical people
expected to do this fix? (This is a rhetorical question to all of fedora-
devel.) Could dnf system-upgrade detect that it's running on a system that
will fail? Could it warn people beforehand or even apply the grub
upgrade first?
I have to think the issue could be detected before upgrading.
d=`mount | awk '$3 == "\/boot" { print $1 }' 2>/dev/null`
if [ "x$d" == "x" ] ; then
d=`mount | awk '$3 == "\/" { print $1 }' 2>/dev/null`
if [ "x$d" == "x" ] ; then
echo "Upgrading your grub2 install to a current version
cannot be done. You should not proceed with upgrading your system."
exit 1
fi
grub2-install $s
if [ $? -ne 0 ] ; then
echo "grub2-install encountered an error. You should not
proceed with upgrading your system."
exit 1
fi
fi
...
Anyways...following the instruction on that page...when
configfile /grub2/grub.cfg.rpmsave
is run, it immediately shows me the menu and boot commences as it did. It
then says: "execute the grub2-install /dev/X command (where X is the boot
device, i.e sda) to update the GRUB core and the module"
This is what happens:
# mount | grep boot
/dev/sda1 on /boot type ext4 (rw,relatime,seclabel)
[root ~]# grub2-install /dev/sda1
Installing for i386-pc platform.
grub2-install: warning: File system `ext2' doesn't support embedding.
grub2-install: warning: Embedding is not possible. GRUB can only be
installed in this setup by using blocklists. However, blocklists are
UNRELIABLE and their use is discouraged..
grub2-install: error: will not proceed with blocklists.
and rebooting the system now has:
error: symbol 'grub_file_progress_hook' not found.
Entering rescue mode...
grub rescue>
Which seems like a big step back from where I was.
