Calibre on Fedora Linux, cannot upload books to Kobo

[ZodWallop]

Hey guys. I'm running Calibre 5.16.1 on Fedora Linux 33. I've installed Kobo Utilities and Kobo Touch Extended (which is I think what is causing my issue).

I'mable to update ePubs to my Nook. But when I try sending books to my Kobo using Kobo Touch Extended, I get the below error message.

calibre, version 5.16.1

I've tried uninstalling and reinstalling Kobo Touch extended.

I did disable the Kobo Touch plug-in.

That suggests the book has errors. From the code, the extended driver is trying to add a file to the manifest and the manifest cannot be found. That suggests the book is invalid, and specifically, the OPF is wrong. I would open the book in the calibre editor and run to check tool to see what errors it produces and then fix them.

Well, I tried using the tool, but the error fixes were above my pay grade.

I deleted the ePub and reconverted and wound up getting the same error. What I failed to mention is after converting but before loading the book, I edited it with Sigil and I think the version of Sigil I have is causing trouble. It's version 0.9.14-7.fc33 from the official Gnome Software repo Fedora uses. But I noticed when using Sigil, it will freeze and stop responding.

I wound up using my Windows PC which got everything squared away.

In the future, I will just use Calibre's built-in ebook editor instead of Sigil and see if that helps.
