"PermissionError: [Errno 13] Permission denied: 'node'" with container builds

[Alan Pope 🍺🐧🐱 🦄]

I have been building a node application (yaml below). I have set SNAPCRAFT_CONTAINER_BUILDS=1. Whenever I 'snapcraft clean' I get the following error:-

I'm using 2.38 (1008) from edge.

PermissionError: [Errno 13] Permission denied: 'node'

Seems snapcraft can't clean up it's own stuff when done with container builds due to permission issues?

I thought that this would be fixed by https://github.com/snapcore/snapcraft/pull/1904, but I just saw a very similar error.

I was building this one: https://github.com/elopio/branch-diff/blob/snapcraft/snap/snapcraft.yaml
with SNAPCRAFT_CONTAINER_BUILDS=local

When I tried to run snapcraft clean, it failed with:
PermissionError: [Errno 13] Permission denied: 'node.1'

The permissions on the install directory are not correct:

kalikiana, can you please take a look at this one?

I have my machine still available if you want me to collect some more info or try something.

Some general observations:
- Upstream has moved to https://github.com/klembot/twinejs
- nwjs-sdk-0.25.4-*.zip is pulled for every available platform

Indeed something about the permissions is off:
