Hi,

I just glanced at the build log you attached. The first thing I saw was meson erroring from an unhandled Python error, and scrolling up quickly revealed the error. It looks like your install phase is failing because it is trying to write outside of the store:

    PermissionError: [Errno 13] Permission denied: '/etc/xdg'

It looks like that project's meson.build hard-codes a reference to a path under /etc/xdg at https://github.com/jack-mixer/jack_mixer/blob/main/meson.build#L49

Cheers,
Kaelyn
