Metasploit service - `remove_stale_pid_file': log/thin.pid already exists

[Youcef]

Hello,
OK now I'm really loosing my mind because of the Metasploit service, I had the error with it before I couldn't fix it so I had to format my PC and have a fresh Kali OS, after installation I had to apt-get update && apt-get dist-upgrade -y update successfull, of course the metasploit service was running like a charm, anyway I installed Google Chrome and made it run as root, than installed PlayOnLinux and runed it as a normal user by adding it adduser youcef, after trying to reboot my PC in rebooting an error was showing so i had it in mind it was metasploit service after booting in again into my OS desktop I started the terminal and
