Cannot build flatpak-builder beacuse no appstream.compose?

Question

I cannot find appstream.compose module. It is needed for flatpak-builder:

$ meson setup _build                   (git)-[main]
$ meson install -C _build

meson.build:45:23: ERROR: Command `/usr/bin/appstreamcli compose --help` failed with status 4.

The problem is that using the standard way of installing the compose module doesn't work:

$ sudo appstreamcli install org.freedesktop.appstream.compose

Unable to find component with ID 'org.freedesktop.appstream.compose'!

So how to install the compose module and build flatpak-builder?

Answer 1

To resolve this, install AppStream compose with your distribution. For example, with Ubuntu or Debian:

apt-get install appstream-compose

Fedora:

dnf install appstream-compose

openSUSE:

zypper in AppStream-compose
