Snapcraft fails to build a package with meson plug-in and including gettext, gschemas and resources. The error message is "ImportError: No module named ‘mesonbuild.modules.i18n’ ", cause the build environment install meson 0.29 version and support for gettext, gschemas and resources has been updated in 0.30 version and so on. A workaround to solve it is to update meson: parts: mypart: after: [desktop-gtk3, snapcraft-preload] source: https://github.com/xxxxxx/yyyyyyyy.git source-type: git plugin: meson meson-parameters: [--prefix=/usr] prepare: | apt-get install -y python-setuptools pip3 install meson
