Installing the KOReader flatpak on ARM

1

Hey,
I’m trying to install the KOReader flatpak on my arm7l machine.

$ flatpak install rocks.koreader.KOReader -v
F: No installations directory in /etc/flatpak/installations.d. Skipping
F: Opening system flatpak installation at path /var/lib/flatpak

error: No remote refs found for ‘rocks.koreader.KOReader’

Initially I thought this was because it isn’t built for my architecture. The page lists aarch64, x86_64 as the supported ones. Then I noticed that other flatpaks with the same support work just fine, for example Sliderule.

Why does Sliderule work and KOReader doesn’t, if they’re both have the same architectures supported?

arm7 is no longer supported on flathub.

Thanks @hub ! So is the reason one app works and the other doesn’t simply that it has arm7 support, but it’s just not listed in the page?

Is there anything I can do about it? I don’t know much about flatpaks - can I “compile” my own arm7 variant based on the flatpak “recipe” somehow?

Thank you!

Why is it not supported anymore?
