That has succeeded sometimes, and failed sometimes, but presently it 
succeeds. (Using the MacPorts distribution of gnucash @5.8_1+docs on macOS.)

I can also, for example, add a security to a book file by using the 
GncCommodity() class. This sample code worked for me:

>>> import gnucash
>>> FILE = "file://./test_book_1.gnucash"
>>> session = gnucash.gnucash_core.Session(FILE)
>>> book = session.book
>>> comms = book.get_table()
>>> qqq = gnucash.gnucash_core.GncCommodity(book, 'QQQ_fullname', 'MySecurityType', 'QQQ', 'QQQ_qsip', 100)
>>> comms.insert(qqq)
>>> session.end()
>>> session.destroy()
>>> quit()

Sorry, I guess I did not follow your meaning. I read you as saying that 
those packages, but not that those packages were actually installed on 
your system.

You have reached the limit of my knowledge, especially concerning 
GnuCash on Linux. Sorry.

Again, yes.  Thus you can be confident that it has worked for someone 
somewhere at some time.
