I worked for a publisher for about 10 years as a typesetter and ebook developer. There are a lot of things about the publishing industry that are antiquated, especially for non-technical publishing companies. Unfortunately it's a low margin business.
Most authors are only familiar with Microsoft Word, so on the front end you often have to take a messily styled Word document and manually caress it into a structured document that can be used for ebooks and print.
For print, a majority of non-technical publishers use Adobe InDesign and/or InCopy. Editors edit manuscripts in InCopy and typesetters style documents for print. PDFs are generally exported and sent to printers via FTP.
For ebooks, every publisher seems to have their own bespoke system. You _can_ export books in epub format from InDesign but the process for getting a clean ebook is difficult to say the least since InDesign was primarily designed for print publications. Generally, you end up structuring books for the lowest common denominator of ebook platform (epub, kindle, etc.) unless you are creating something like a children's book or a poetry book where you might do something more custom.
Many publishers use ebook distribution platforms where you upload epub, mobi, cover images via FTP. They use an XML standard called ONIX for distributing metadata that's unique to say the least...
I oversee ebook production for a university press publisher, and indeed, our typesetters have to do some pre-processing of our authors' Word files before typesetting (we do all editing and copyediting in Word), and then post-processing of the Indesign output to get acceptable ebook files. There are some plugins that will help. Indesign, left to its own devices, will give you garbage.
Our sales vendors all check the files with epubcheck. If it doesn't pass, they'll bounce it.

I wonder if that's why so many, and even relatively new, ePubs feel a lot like poorly OCRed PDFs?
It generally seems like most publishers and I have opposite goals when it comes to ePubs: They want them to look and feel as much like the physical book as possible (by including custom fonts, applying custom margins/padding etc.), while I want absolutely none of that.
It's frustrating having to fight the publisher to get something readable on a small display or non-Kindle ePub reader, and I don't even want to get started on dark mode...
There are two kinds of epub layouts, reflowable (the good kind) and fixed-page (the badly OCR'd feeling kind). Most print designers who don't follow best practices in turn don't do the work required to make InDesign output reflowable epubs.
Reflowable epubs in InDesign require discipline that a lot of print designers (and even some full-time typesetters) lack. You have to use a single content flow (all text must be linked between text frames in one unbroken flow), any images and sidebars must be anchored in that flow (you can't just freely place them on the page), and you have to consistently use paragraph and character stylesheets (i.e. you can't just ctrl-B embolden text, etc., you have to create/use a "Bold" character sheet).
It's hard to call that "difficult" because those are already best practices for print, but they aren't intuitive to most people and InDesign doesn't make it easy to track how much of this you're doing correctly or flag which parts you've done wrong.
FWIW I’ve published a few of my own books. I write them in latex to get perfect print ready pdfs, then pan doc gives me flawless epub files, all from the same source.
It works really well
Any special LaTeX packages you are using?

Great read. Thanks!
Not OP but I basically do the same thing (except the epub part) and the secret is to use XeTeX, since it allows you to use modern fonts.
This is extremely helpful information [0]. Thank you.

Is noone using Apple‘s Pages app? I hear it‘s decent for creating EPUB files.
Cutting and pasting an old 2019 comment https://news.ycombinator.com/item?id=19944627 :
> There are similar problems with uploading to publishers in ePub format. The last time I was bashing my head against ebook publishing, about a couple of years ago, many (most? all?) of the sites were validating ePub uploads using an old version of the ePub suite which rejected some ebooks which were valid per the up-to-date validator. Which version they were using was ofc not documented, and you were lucky to even get to see an error message. And of course tech support was largely unhelpful. (Especially kobo.com 's.) The people working on the ePub spec seemed to be largely unbothered by the fragmentation/noncompliance and hideous experience for those authoring and uploading in the format, too.
> Which is a pity, because aside from this and some other bugs and pitfalls EPUB 2.0 has some attractive features and is nice to work with for anyone who doesn't mind bashing out a good old directory tree of HTML docs by hand.
Maybe things are a lot better by now. Here's hoping!
Why is this linked now? There's no new release or milestone at this time.
Citing my comment from when this was new about eight months ago:
> Even more unfortunate is that this change has already spilled to derived standards such as EPUB3 which hence makes existing EPUB3 content using compound headings going back to 2011 invalid, and EPUB3 writers lacking a tool for actually verifying what readers can support (epubcheck was blindly updated without consideration for the installed base).
See also the blog [1] about W3C's most recent HTML spec. Lack of HTML backward compat along with gross import of all of CSS without profiles, or paged media requirements and deemphasis of long-standing EPub mechanisms in favor of CSS and JS, and general impression of a low-effort, merely editorial nature really makes Epub's move to W3C questionable but nobody seems to care anyway, sticking with EPub 2 and 3.1 (which is also what Calibre is recommending as target format for conversion).
One can also $(brew install epubcheck) if so inclined https://formulae.brew.sh/formula/epubcheck#default
Or `nix run nixpkgs#epubcheck`

I'm not sure why but when I download some epubs and try to send to my kindle it fails. Only after using an online converter to convert them from epub to epub does it then work.
You might want to try running the EPUB through https://kindle-epub-fix.netlify.app/
This applies a few fixes for problems with EPUBs that the Send to Kindle service doesn't like.
Maybe a little less hassle than using some web thingy. Ebook-convert is a cli application that comes with Calibre, and is probably what the online sites are using anyway.
ebook-convert infilename.epub outfilename.epub
The "online site"/"web thingy" linked in another comment is
1. like 300 lines of code <https://github.com/innocenat/kindle-epub-fix/blob/master/scr...>
2. runs entirely in the browser and isn't using Calibre scripts or anything else
3. could pretty easily be modified into a downloadable program that runs from both the command-line or something that you can open in your browser
I've used Calibre with the KFX Output plugin for years, never had an issue with converting pirated epubs.
Tried to publish an epub to German platform Tolino, tried everything, tried an external service agency, etc. doctored around in Calibre, no success, they didn't accept the epub.
Printed PDF for decades at print shops, never had a problem.
Why is this such a problem? Because of the HTML?JS?
I believe epub is just a zip archive of html. Could you extract the files and then use a html validator which would cleanup the presumably broken markup?
My initial attempt would be to use pandoc to roundtrip the files.
Genuinely thankful for this tool and use it for both sides of my non-fiction book project (research: verifying converted or misbehaving epubs for use on Remarkable, iPad, Calibre and Kindle (I know, I know...)) as well as typesetting and review.
