...i have NO clue what to do here, other than per instructions, let alone how to read/interpret the following - assistance mucho appreciato![attachment=245]

This may be a known problem in which an update appears to fail but actually completes behind the scenes

Please can you open a terminal by pressing 'Ctrl' 'Alt' and 'T' together.
Type or paste in this command followed by enter.  This will refresh the update cache.
Enter your password if asked.

Then enter this command which will calculate if any programs need upgrading and if so, it will ask if you wish to apply them.
You can answer 'n' if asked, we are interested in what upgrades the system reports being as required.


Each command creates a text file in your home directory in which the screen output is saved.
After running the two commands please review the two text files and paste the results back here.

Thank you

...reports/labels it as an "empty document"

That looks better.
The 'could not get lock' error message indicates more than one update processes are competing for the resources. There may have been a background task running. Leave it for 10 minutes and then try an update/upgrade again.
