wsl.exe stdin upload failed (status {:?}): {}

Error message

wsl.exe stdin upload failed (status {:?}): {}

What it means

During stream_file_into_wsl, the wsl.exe child process that receives file bytes on stdin exited with a non-success status; the status and stderr are embedded in this error to explain the failed upload.

Solutions

1. Check disk space and permissions inside the WSL distribution
2. Re-run the upload; transient wsl.exe failures often succeed on retry
3. Verify wsl.exe and the target distribution are healthy (`wsl -l -v`)
4. Inspect the captured stderr in the error for the wsl-side failure
