fix #181

Restart journald command

Need to use `sudo apt` if not root user. proceeding 2 lines already incorporate `sudo` commands so for consistency these lines should be `sudo` too.

- Move "Is it working?" section to after "Install"
- Adjust "Is it working?" a bit, mention "systemctl status"
- Wording
- Add Troubleshooting section with journal cleanup tips
