Build VM status summary

I wrote up a quick summary/walkthrough with some short videos on for those wanting a quick summary of the status of Status Tracking for Build VM

have you thought about documenting which snapcraft version/channel we need? The statement that “you just need to run snapcraft to get a resulting snap. Given that we set the base to core18 a virtual machine will be setup” is wrong:

$ snapcraft

I do have base: core18 in my snapcraft.yaml.

$ snapcraft version
snapcraft, version 2.42.1

I am showing rather unreleased code :slight_smile: Maybe I should have written, all you _will_need to do.

You need to be on edge/bases, set SNAPCRAFT_BUILD_ENVIRONMENT=qemu and install (for now) qemu-system-x86 and cloud-utils.

excellent, thanks, I’ll give it a gander :slight_smile:

Feel free to reach out on irc or telegram for an expedited getting started, I do acknowledge that it might be to early if you want click and run :slight_smile:

the snapcraft:edge/bases snap is missing cloud-localds which is in the apt package cloud-image-utils. Installing via apt to my host gets past the error.

building gimp locally using the edge/bases snapcraft channel with SNAPCRAFT_BUILD_ENVIRONMENT=qemu in the environment I successfully finish the build up to the point where it tries to assemble the final snap from prime/. Here it fails complaining that the .desktop file I’ve told it to use for gimp isn’t where I said it would be. It is wrong:

Priming gimp 
Priming scripts 
Failed to generate snap metadata: The path 'prime/usr/share/applications/gimp.desktop' set for 'desktop' in 'gimp' does not exist. Make sure that the files are in the `prime` directory.
An error occurred. Dropping into a debug shell.
Last login: Wed Aug 22 23:17:46 2018 from
gimp # ls prime/usr/share/applications/gimp.desktop

As you can see I execute an ls in the debug shell (the paste above is from when I ran a second time with --debug to diagnose the problem after encountering it) with the path it says isn’t present. The ls output clearly says that the file is correctly in the location snapcraft says it is looking for it.

Thanks, this is indeed a bug, how to fix it depends on how that desktop file entry is declared as it seems that path is hardcoded somewhere.

I’ve declared it with the following:

    command: desktop-launch $SNAP/usr/bin/gimp
    desktop: usr/share/applications/gimp.desktop
    plugs: [...]

In previous builds that correctly finds the desktop file in the prime directory which is installed there by my build process. With the qemu build, though, it doesn’t find it at all.

great, so it is a bug in our code base most likely, I’ll have to look through it and make sure the abspath for prime is used.
It does not find it in the qemu scenario (nor multipass, it is somewhat enabled for this mode too, just a little slower) because parts, stage and prime are no longer collocated with your source.
