You might try to see if Calibre can read and convert the file, https://bugs.kde.org/show_bug.cgi?id=475975#c5 Two possible explanations: - Some distributions have started to enable the QMobipocket depedency for KFileMetaData - Download & Transfer for Kindle eBooks Going Away on February 26 [1] [1] https://blog.the-ebook-reader.com/2025/02/12/download-transfer-for-kindle-ebooks-going-away-on-february-26/ Git commit a188b893654fe5f88b1ebab7e8341ceb181f6dc9 by Stefan Brüns.

[MobiExtractor] Disable buggy text extraction by default
The text extraction in mobiextractor is extremely buggy, and causes
a lot of bug reports for baloo (which then gets blamed for its
"buggyness" when calling third-party code).
QMobipocket lacks support for any halfway current mobipocket version
(last supported: 4, current: 8), and has no testsuite.
Make this opt-in ("ENABLE_MOBIPOCKET_TEXT_EXTRACTION") until the bugs
in QMobiPocket gets fixed.

A possibly relevant merge request was started @ https://invent.kde.org/graphics/kdegraphics-mobipocket/-/merge_requests/35 Git commit 439a01662e72102e114a46d168fbabbb4de04184 by Stefan Brüns. Committed on 07/06/2025 at 15:19. Pushed by bruns into branch 'master'. Handle trailing data entries correctly Text records may contain extra auxiliary data which should not be fed to the decompressor. The existence of such data is signalled by the `extraflags` header field, and each set bit signals the corresponding extra data which will be present in all text records. The entries can be decoded (or removed) by reading the record from the back. When an entry is present, its size will be at the very end of the record, preceded by the actual data.
