Snapcraft crashing when using alsa parts manually in snap

I can’t seems to build using alsa parts manually even tried with fresh snapcraft.yaml.

And I know I can use below alsa parts to build snap fine but I want to use different PATHS on configdir and plugindir for content interface.

    after: [alsa-plugins, alsa-lib]
    after: [alsa-lib]

I’m getting into this error when locally building the snap.

Sorry, Snapcraft ran into an error when trying to running through its
lifecycle that generated a trace that has been put in '/tmp/tmpycfhw0sg/trace.txt'.

your indentation is screwed-up. you’ve set the alsa definition as top-level, not nested beneath parts:. Also, alsa-lib definition is not indented properly - one space instead of two (two spaces are required because that’s what you used for enable-i386.)


oops silly me:man_facepalming: good catch daniel :+1:
