Appstreamcli started failing with my flatpak

Since about one month appstreamcli started failing:

Running appstreamcli compose
Only accepting components: com.github.makhber.Makhber, com.github.makhber.Makhber.desktop
Processing directory: /home/runner/work/makhber/makhber/build/.flatpak-builder/rofiles/rofiles-Etyc55/files

  E: file-read-error
Error: ERROR: appstreamcli compose failed: Child process exited with code 1

This is my project makhber/packaging/flatpak at master · Makhber/makhber · GitHub
Please tell me if there is something wrong.

As an update, the failure only happens on Ubuntu 24.04 It doesn’t happen on Ubuntu 22.04.

Maybe something todo with appstream 1.0.2 vs 0.15.2?

Could be but that’s an appstream question not for here. If you are using it to submit it on Flathub, use org.flatpak.Builder as the docs say.

I don’t understand what are you suggesting?

Should I report the issue to appstream or flatpak?
