Your question:

When I follow the install guide from https://manticoresearch.com/install/ about WSL, the last step sudo systemctl start manticore did not work:

$ sudo systemctl start manticore

Job for manticore.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status manticore.service" and "journalctl -xeu manticore.service" for details.

$ sudo systemctl status manticore
