Upgrade from 2.3.4 to 2.4.2 now no GUI or SSH

[penbrock]

I tried to install the update from the web GUI from 2.3.4 amd64 to 2.4.2.
Everything seems to be working other then that

I received no error message but after the reboot when I try to log in I get 504 gateway timeout error.

If I try to putty to it, it has a fatal error 'Disconnected: Server protocol violation: unexpected SSH2_MSG_UNIMPLEMENTED packet'

The console shows it is still running 2.3.4  and if I try 13 to upgrade the first error line is that /var/db/pkg/repo-p(?).sqlite is missing
I looked in the folder and the closest file is local.sqlite

Any idea what a newbie can do to fix this?

Are you running nano or otherwise on a small storage system?

I have it running on an old HP dual core I had

I found that I can get to the GUI using http://192.168.2.1/system.php.

I went right to System/Update to try to fix the update but it reply's with
