That was going to be my next email. The fact that the GUI shows me the
updates and when I click on "Install Updates", it goes back to checking for
updates and does not actually do the update. So I stopped it, and ran
freebsd-update fetch and freebsd-update install and ended up with this
botched upgrade. After restoring the files, I was able to run this from
command line again with no issues. The GUI just brings me the updates
available and no updates are installed. I wonder why...
This is being run from my laptop.
Of course, you might discount this possibility, but remember that one in a
million chances happen 99% of the time.
