Bug#1144836: rust-swaysome: autopkgtest fails under incus-lxc: failed to execute 'kill': Os { code: 2, kind: NotFound, message: "No such file or directory" }

[Skia]

Thanks for the bug report.
It seems to be just due to a missing test dependency, I've opened a Salsa MR to 
fix that:

I'll look for someone to kindly merge it and upload.
