Importing failed almost totally

[pier59]

Hello,
I have just started installing Calibre and I added 1980 epub books.
I meant to sync them with my Kobo Glo (bought 15 years ago). I wanted to put them on a new, empty SD card, and only 49 books got transferred.Here are the messages that I get:

calibre, version 8.8.0
AVERTISSEMENT : Pas de format adapté: Impossible d’envoyer les livres suivants vers le périphérique, car aucun format approprié n’a été trouvé. Convertissez d'abord le(s) livre(s) vers un format pris en charge par votre périphérique.

Des vents contraires
Les Lisières
and many other books not transferred

And here is the translation : calibre, version 8.8.0
WARNING: No suitable format: The following books could not be sent to the device because no suitable format was found. First, convert the book(s) to a format supported by your device.


And another pop up :

calibre, version 8.8.0
ERREUR : Erreur: Erreur pendant la communication avec le périphérique

Translated as:

Merci de votre aide.

That error means the EPUB file you are trying to send is corrupted. You can try doing an EPUB to EPUB conversion which might fix it as the conversion code tried hard to workaround corruption.

I wonder if the issue might be related to the length of the filename...

I wonder if this could be a MacOS issue.
