Calibre 6.3 DeDrm 7.2.1 import

[Patriks999]

Hi!
I recently started to have problems with importing books to Calibre.
I get the following message;

"C:\Users\Joe\AppData\Local\Temp\calibre_ss14bw2u\m0xuc3hz_add_books\0\Ner i mörkret.epub

With errors:
Traceback (most recent call last):
File "calibre\gui2\add.py", line 456, in add_book
File "calibre\db\legacy.py", line 333, in create_book_entry
File "calibre\db\cache.py", line 77, in call_func_with_lock
File "calibre\db\cache.py", line 1974, in create_book_entry
File "calibre\db\cache.py", line 1672, in set_metadata

File "calibre\db\backend.py", line 1020, in execute
apsw.CantOpenError: CantOpenError: unable to open database file"

Do any of you have the same problem and maybe found a solution?

Thanks for any suggestions

For calibre 6.x, you need DeDRM 10.0.3: https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.3

Hello and thank you for your answer!
Unfortunately I get the same error as before;
calibre, version 6.3.0
FEL: Fel vid tilläggning: Det gick inte att lägga till böcker, klicka "Visa detaljer" för mer information

Do you think it´s related to the Dedrm or a problem with Calibre or maybe something else
Thanks

Something is blocking calibre from writing to its database. An anti-virus program?

[Patriks999]

Thanks but I tried disabling Norton with the same result. I have now changed the location of the library to my laptop and that works. The database has been on my Openmediavault for years without problems but I guess something has changed...
