try to run
bash /home/m1/4update
after it downloaded the files
run
bash /home/m1/2unix
see how it goes.
That worked! After running the 1st part, it got stuck again trying to open a 2nd window, but I just did a ctrl-c and then ran the 2nd command.
When it was done and rebooted, I copied my 19.1-1 1bash file over, but it then tried to update to 19.1-2 again. So I modified the 19.1-2 1bash instead and I'm mining again.
So the above trick should work for doing a manual update over ssh where you can't pop a 2nd screen?
If I remember correct, 2unix runs in gnome-terminal and that needs to run locally
