Calibre Sync broken by Calibre v9?

Should be scriptable.

Yes, it's quite fast and it's maintaned between updates.

I've tried reverting to 8 and it seems to have worked, I haven't done any exhaustive testing, but the error message has disappeared and one other problem has been resolved. Really early days, but looks promising.

Briefly, I downloaded Calibre 8.16.2 installer, exported the Calibre 9 Library ( not used in the end ), renamed the metadata.db, installed 8.16.2, ran the restore database option, ( ran MegaSync to sync my Box Calibre Library to its copy on Mega, which is what my Sync looks at, not relevant to anyone but me ), ran Calibre Sync, it updated it's database with no errors and seems to work ok.

The problem I mentioned was to do with series changes, the changes showed up correctly in the series filter, but when you looked at the actual book it still had the original series information displayed.

I'll do some more testing when I get the time.

I’ve just found this thread and at least it explains why calibre sync doesn’t work anymore. Tbh I don’t understand it, or the workaround. It’s a pity it’s not maintained anymore.
