I changed all the KoboTouch driver and other plugins to use apsw as this uses a later SQLite library and is what calibre uses for all of it's own database access. After making the appropriate changes to Obok, the books could be seen, but the DRM could not be removed. It could for a 3.19 database on one of my devices.

Thank you for the tip!
I bought a book from Kobo and the Obok tool raised the error regarding the uncompatible or encrypted database.
I tried to modify OBOK.PY file by changing 'sqlite3' by 'apsw' and 'fetchone' by 'next', but know the plugin complains about the database not containing valid keys...may I need more changes to use APSW? (I asume the keys are there, but the use os 'apsw' makes the script fail, maybe because the returned data when using 'apsw' is not the same as 'sqlite3').
Yes, I know I can install and use ADE, but I would prefer to have the obok plugin fixed.
I would appreciate some guidance on what changes between 'sqlite3' and 'apsw' besides 'next' instead of 'fetchone', and 'Connection' instead of 'connect'.
Thank you!
