flatpak Error during processing MOBI

[mrtn619]

I'm on linux, I've installed KCC through flathub, put kindlegen_linux_i386 to ~/.var/app/io.github.ciromattia.kcc/data/kindlegen and granted the host permision using flatseal but for some reason it does not work. I've tried using pdf, images, but nothing seems to work I've launched KCC from terminal and this is the error log I've recieved:

@mrtn619 does removing the period in the file name fix it? Aka 'pdf.io'

[Lokiavanger]

I'm having the same issue listed here. It generates all the EPUBs and then the first EPUB disappears and the app hangs. I'm on Ubuntu 24.04 running the Flatpak version. I have subfolders of images that are being converted.

Let me know if there is more information I can provide. Thank you!

@Lokiavanger can you try downgrading kcc to 5.6.5 and 5.6.4 to see if issue still occurs?

[Lokiavanger]

@axu2 I'm getting the same error on 5.6.5 which is the oldest commit I see on flathub. That is commit a3971a6ee39deb4bf56733525eaac6a63589ea621d3681ff67c8b401e636736b.

Thanks again!

@Lokiavanger @mrtn619

1) Run KCC but output to epub 2) run the following python snippet on your machine and tell me the output. Don't forget to replace kindlegen and placeholder_manga.epub with the absolute paths. This is what KCC runs to create the mobi but it seems it isn't being created for you.

import subprocess
subprocess.run(['kindlegen', '-dont_append_source', '-locale', 'en', 'placeholder_manga.epub'], stdout=PIPE, stderr=STDOUT, encoding='UTF-8')

[Lokiavanger]

Hopefully I did this correctly. I ran this from a python interactive session. Not sure if I should be installing qemu based on the output. Thank you.

[Lokiavanger]

A few updates. I have a laptop running openSUSE and I'm having the same issue there with the flatpak version. I installed qemu-user and now I'm not getting that error but I'm also not seeing a MOBI file. I checked the working directory and there's nothing and nothing in the directory with the epub. Still getting the same error in the app as well.

Thank you.

[axu2]

Try: @Lokiavanger

Weird it says return code is 1,

subprocess.run(['/var/lib/flatpak/app/io.github.ciromattia.kcc/x86_64/stable/a3971a6ee39deb4bf56733525eaac6a63589ea621d3681ff67c8b401e636736b/files/bin/kindlegen', '-dont_append_source', '-locale', 'en', '/home/loki/Documents/Mangas/Battle Royale 2.epub'], capture_output=True, check=True)

[Lokiavanger]

This is what I get.

[axu2]

@Lokiavanger can you try it one more time but remove the check=true part?

And then also remove the capture output part.

Kindlegen appears to be throwing an error but not showing any error message besides the nonzero return code.

[Lokiavanger]

It looks like it's unable to find the kindlegen file, but I can attest that it's there.

Not sure how to get end lines formatted in the code blocks, sorry.

@Lokiavanger

Does anything here help?

[Lokiavanger]

Yes! I'm not sure how I didnt find this by searching... I didn't realize I needed to seek out kindlegen and put it in a specific directory for this to work.

I found a copy of kindlegen_linux_2.6_i386_v2_9 and moved the kindlegen file to ~/.var/app/io.github.ciromattia.kcc/data and everything generated as expected. Thanks so much for your help!
