Problem with nix direct install

[pjz]

Sorry I can't offer much help, I'm still learning nix flakes and such. I can't even tell if this is really a problem with task-keeper or with one of its dependencies.

$ nix shell github:linux-china/task-keeper
error: builder for '/nix/store/cy07c76bwi83am9y11x1yffzzbicin99-task-keeper-deps-0.30.8.drv' failed with exit code 101;
