You can delete metadata.db (keep a backup just in case) in your calibre library folder. Then calibre will startup with no books. Then follow the restore database procedure, described here: http://manual.calibre-ebook.com/faq....libre-is-blank

Hi Kovid, I'm having the same error. I did what you said twice and it didn´t work. I recently updates my laptop with windows 10, and the error appeared when I updated to calibre 2.49, a couple of days ago. Here is what it says after trying to restore the library:

calibre, version 2.49.0

I hope you can help me to fix this. Thanks in advance.

That's just an error in reporting success, probably because you have some non-ascii encoded files in your library folder, or the path to you library folder contains non-ascii characters. I have fixed the reporting code to handle this in the future. In the meantime you can always restore from the command line instead, like this

calibredb restore_database -r

Hi again Kovid, thanks a lot for answering so quickly. I did what you said and worked perfectly!!. The metadata is completely recovered and Calibre running without issues.

Thank you so much for your help and for making sure this software available for us.

Best.

A.

Hello after updating to the last version before this it is not possible to add new books. I make an Update to 2.59 und I restored the database you described.
Here is my error

What can I do?

Thank for reply Olli

[kovidgoyal]

Remove ALTE GER\xc4TE from your environment variables

[Olli1967]

Hello,
thanks for your quick answer. But I have not a variable like ALTE GER\xc4TE.
Best regards Olli

[kovidgoyal]

It will look like ALTE GER<something>TE and it may not be all uppercase, but it is there. Or just wait for the next calibre release which has a fix for this issue https://github.com/kovidgoyal/calibr...295a59a2778ea1

[jhowell]

ALTE GER\xc4TE --> Alte Geräte ("Old equipment" in English)

[Olli1967]

Hello the name of the variable in germany is
Alte Geräte I deleted it and calibre works well.
Thanks

That happens when I connect my Kobo with Calibre.
is it a problem only on PC or a problem on memory of Kobo ?
It seems for me that it's a problem on Calibre Database on PC.
Must I try to restore database in Clibre ?

Thanks for your response.

Thanks for your response.

If it happens ONLY with the Kobo attached... It is the Kobo

I believe the advice is to log the Kobo device OFF (frm Kobo.com?), then back on. This rebuilds the device DB

[philmagic59]

Thanks for your response.
I am reconstructing in Calibre a copy of directory of my books.
So I cannot use Calibre to try what you tell me to do.
But yesterday I reinitialized my Kobo, and I have always same problem. And Windows 8.1 tells me that I have not problems on the memory of my Kobo.
Again thank you.
