Hallo,
just installed 5.3.0 over 5.0.1 on my Ubuntu 18.04 LTS System. Never tried Metadata and Cover download before but it seem that it's not working. Tried on some books (not bulk modus) and on each book I get the same Error:
calibre, version 5.3.0 (German)
--------
FEHLER: Herunterladen fehlgeschlagen: Herunterladen der Metadaten oder Titelbilder für das ausgewählte Buch fehlgeschlagen.
<autorsurname>, <autoname> (Fehlerhafte Metadaten) (Fehlerhaftes Titelbild)
-------------
I started in debug mode but no further details. Can you tell me how to get more details about that error. I am not sure if my firewall blocks something or if there are really no metadata in the www.
Regards
Frank
