Failed to download stage packages for desktop-qt5 in zesty

[larryprice]

When trying to build with the desktop-qt5 helper on zesty, I get the following error:

Error downloading stage packages for part 'desktop-qt5': The package 'appmenu-qt5' was not found.

Using rmadison, it's clear that appmenu-qt5 is not currently available in zesty. This will likely become a more common issue in the next couple of weeks when zesty is finally released.

Just ran into this while trying make a few adjustments to the robomongo snap: https://github.com/frankban/robomongo-snap/blob/master/snapcraft.yaml#L16

Any workaround?

Zesty has been released, and this is still a blocking issue.

I'm using after: [desktop-qt5] as [desktop/qt5] complains / is deprecated.

Looking through the snapcraft codebase, there doesn't seem to be a way to specify installing from archives that aren't the current release.

I'm beginning to think this part might be abandoned. I see that the tests are only testing the deprecated desktop/qt5 instead of desktop-qt5, and don't actually test the local version (though this may be a limitation of snapcraft). I also cannot build this plugin locally (even removing appmenu-qt5) because of an issue with conflicting filesets.

Having said that, I've created a workaround. It's not the prettiest solution, but it should get the job done for now: https://github.com/larryprice/snapcraft-desktop-qt5. YMMV, but this makes the demo work for me at the very least.

As you told, there is unfortunately no mechanism in snapcraft to do this per release, and appmenu-qt5 is still needed in Xenial for instance, which is the base distro version used for them.
Note that you can override parts of a remote part definition (see http://blog.sergiusens.org/posts/The-Snapcraft-Parts-Ecosystem/), which will make you only override the stage-packages definition and not the whole logic.

The following snippet makes this work on 17.04:

parts:
  app:
    source: .
    after: [desktop-qt5]
  desktop-qt5:
    stage-packages:
      - libxkbcommon0
      - ttf-ubuntu-font-family
      - dmz-cursor-theme
      - light-themes
      - shared-mime-info
      - libqt5gui5
      - libgdk-pixbuf2.0-0
      - libqt5svg5 # for loading icon themes which are svg
      - locales-all

I think just using an LXC container or snapcraft cleanbuild is usally fine. That way you also guarantee every project contributor builds with the same environment.
