Error communicating with device

MarkWillCry · Yesterday, 07:22 PM

After a year of using calibre, I have acquired a new device and, therefore, a new error that gives me following details:

calibre, version 9.13.0
ERROR: Error: Error communicating with device

database disk image is malformed

Traceback (most recent call last):
File "calibre\gui2\device.py", line 107, in run
File "calibre\gui2\device.py", line 593, in _books
File "calibre\devices\kobo\driver.py", line 2390, in books
File "C:\t\t\apsw-39uykmzm\src\cursor.c", line 223, in resetcursor
apsw.CorruptError: database disk image is malformed

I have attempted:
"turning it off and on again" a couple of times
updating calibre
updating plugins
going to the previous version of calibre
returning to the current version
deleting driveinfo and metadata files

However, nothing changed.
Any guesses on what will finally fix this?
Thanks for help!

The database on the Kobo is corrupt. You need to sign it out the Kobo account, then sign back in.
You will most likely lose your reading positions unless you left WiFi on and it had synced with your account.
OTOH if you use Kobo Utilities, and have it save copies of the older DB, you could restore from a older one.

Always Eject and wait for the Kobo to settle (it shows 'Processing' if you added A BOOK) back on the Library screen. DB updates (series and stuff need to get done )
