Calibre doesn't publish arm binaries, therefore this image is x86_64 only

[kfstorm]

Why not update the Supported Architectures section in README.md?

[aptalca]

? It's updated

[kfstorm]

Oh, I just found that arm64 and armhf are recently added (d6d4721bf5e3f47238c12387c3a99954c5e415e2). Does that mean it works now on arm devices with the nightly build?

[kfstorm]

I just tried the lastest image today and it doesn't work on my R4S and the logs are the same as the issue description.

[aptalca]

Only works with the arch tag as listed

[kfstorm]

I see. Any plan to build multi-platform images?

[aptalca]

??

On an arm device, use lscr.io/linuxserver/calibre:arch as that one is multi-arch as listed in the readme

[kfstorm]

Thanks for the clarification! 👍

But why not reuse the latest tag for the multi-arch image? It should be a common practice and I've seen it in other linuxserver images like sonarr and jackett.

[Roxedus]

We want help from our users to test the arch based one, before considering it stable enough for latest.

[Luttik]

Maybe I'm mistaken, but I feel like the Raspberry pi is currently the defacto way to self-host stuff (as a private individual). Therefore I think folding arch into latest should be a top priority. As far as I know, this docker is purely for self-hosting so this might be an issue that most potential users are stumbling into.

(I love the work on this so this is not a value statement about the work but if these assumptions are correct (they might not) having them in the thread seems relevant)

I change my docker-compose with the arch tag and doesn't even start. Log:

Error response from daemon: manifest unknown

Don't want to speak for the whole team but pretty sure most (if not all) of us don't share that belief. Rpi is an entry level device for self hosting and is good for hosting a few services but not beefy enough for more than that (especially the heavy ones like these rdesktop-gui based ones).

You need to provide more than a basic statement and a single line snippet
