minimumCmd execution failed: %w

Error message

minimumCmd execution failed: %w

What it means

Raised in the progress widget's Refresh when the configured minimumCmd shell command exits with an error or produces no output — the widget cannot determine the minimum value of the progress range, so it records the error and displays it instead of the bar.

Solutions

1. Run minimumCmd manually in the configured shell to reproduce the failure
2. Check the command exists on PATH or use an absolute path
3. Ensure the command prints a numeric value to stdout and exits 0
4. Verify the SHELL environment variable is set (the command runs via $SHELL -c)
