Anybody can tell me what does this mean?!

Thanks!

Very bad news. That is telling you that the database image on your Kobo has been damaged. If you have not configured the database backup in calibre, you can try sigining out and signing back in on your Kobo which will generate a new database and then import any sideloaded ebooks. You will lose any book stats.

To setup the automated backup, click on the arrow beside the KoboUtilities icon and select Customize plug-in. On the Devices tab, click on on of the backup options (I use the daily one). Under destination, browse to a location to store the backups. I use Copies to keep to save 5 copies to keep disk space use down and use the Compress database with config files. This will save your configuration no more than once per day as a .zip file.

If you have configured backing up your Kobo database on connect, you can copy the KoboReader.sqlite file found in the backup to your Kobo's .kobo directory.

Edit: The most common cause for database corruption that I've found is not safely ejecting your Kobo before unplugging the USB cable. Generally, I wait for the Kobo to start importing or to return to the GUI before I pull the cable.

It means exactly what it said. The database on the device is corrupt and unreadable. To recover from that, you will need to either restore a backup of the database or sign out of your Kobo account on the device and sign back in. That will recreate the database and import any sideloaded books again. Unfortunately, you will lose the reading status and annotations for these books.

Thank you for your help.

Fortunately, this is not very bad news for me. I don't care much about the reading stats.

I signed out of the account on the Kobo device - this led to setting up the Kobo device again - no problem there.
And I was able to connect the Kobo device to Calibre Portable, delete a title from the device and add a title to the device.

So, for the time being, I'm good.

I am left with the problem of not being able to install the 2 Calibre .msi that I tried, although I was able to install another .msi.

Well, I now tried to instal calibre-64bit-6.2.1.msi - failed as all previous Calibre .msi.

Am I condemned to the Calibre Portable for ever?

FWIW, this just happened to me & the problem was a faulty kobo update. Calibre was happy once I did a factory reset of my device.

Thanks. Interesting that you say it was the fault of the Kobo update - it worked with Calibre Portable.

At the time, I did not want to re-install my system.
However, I recently had to do it (new hard drive) and all went well with the installation of Calibre's latest version
