[GNC] building gnucash on ubuntu 20.04

[John Griessen]

I've been using flatpak 4.8-1 on ubuntu, but it has some glitches in the GUI selection of check boxes on an invoice such as 
taxable, tax included, tax table.  To get those to be changed takes mousing and clicking several places in the line item or it 
just reverts when I go to the next line.


So, I followed the 4.8 build instructions, first getting build deps, and using ninja.
Here is where it stopped:

I tried install anyway:

What to do next?
