Updated the library file "/usr/lib64/calibre/calibre/utils/fonts/sfnt/loca.py" with the patch as suggested. But I got this error instead:

I guess this is a separate bug. I don't have a problem with setUrlRequestInterceptor but I suspect that is the particular .epub files I was trying. I see a mention of this upstream: https://bugs.launchpad.net/calibre/+bug/1850835 Do you have a problem with the file I used to test (/usr/share/calibre/quick_start/eng.epub) which is part of the calibre documentation? i.e. do you have a separate problem or is it my fix, that is causing a problem. I think the former. (In reply to nvwarr from comment #2) > I guess this is a separate bug.

I think the former. Hi, thanks for your quick reply. I didn't use your example file, but another e-book so the reproduction steps is moot. I was a bit quick on reporting this issue. However, the issue is not present in the latest upstream binary release[1], which is 5.6 at this time. Using the latest upstream version works as intended. I have no further quarrels with the version available in Fedora, since I circumvented it. Looking forward to the 5.6 release. [1]: https://calibre-ebook.com/download_linux I'll close this… We have the newer versions in later Fedora releases, let's concentrate on keeping the versions up to date there.
