System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down

As an AI language model, I don't have access to your system's logs, but I can provide you with some general troubleshooting steps to resolve this issue:

1. Check if systemd is installed on your system. You can do this by running the command "systemctl --version". If it's not installed, install it using your system's package manager.

2. Check if your system is using systemd as the default init system. You can check this by running the command "ps -p 1 -o comm=". If it shows "systemd", then your system is using systemd as the default init system. If not, you may need to configure your system to use systemd as the default init system.

3. Check if there are any issues with your system's hardware or network connectivity. The error message "Failed to connect to bus: Host is down" suggests that there may be an issue with your system's network connectivity. You can try restarting your system, checking your network connections, and making sure that all hardware components are functioning properly.

4. If none of the above steps resolve the issue, you may need to consult your system's documentation or seek assistance from a professional IT technician.
