Well, I've not experienced this issue personally. But just did a bit of
googling  / reading and the only thing I could find mentioned a read only
file system having the journaling = true option set in fstab.

You can read the post I read here:

I think it is safe to say that the system is intentionally shutting down.
But of course why, we do not know yet. But pasting that error message into
google and searching did turn up several hits referring to data corruption.
Is it possible the image you downloaded is somehow corrupted ? I remember
back several years ago when we used to be satellite internet, downloading
files of this nature would get corrupted all the time.
