How to deal with the ERROR: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open “/var/lib/dbus/machine-id”

-
After I deployed the scrapy-splash, I ran my spider and encountered an ERROR: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open “/var/lib/dbus/machine-id”

It seemed that no affection to the results but really annoying. After I tried a few solutions from Google, finally I solved it with this command:
dbus-uuidgen > /var/lib/dbus/machine-id

Good Luck!

First of all, you will need to deploy a VPS with KVM technology as BBR does not support OpenVZ but KVM. I recommend Bandwagonhost and Vultr because of the price. Here is the link to register and deploy: Bandwagonhost Vultr (Or click here to get a big discount, only available for a LIMITED TIME ) Here I suggest you choose Ubuntu 16.04 or later versions as your OS. After everything is ready and you can successfully ping your server from your local environment, connect to your VPS via SSH. Now let's start. Step 1: V2RAY V2RAY is a new generation of software for data proxy. It supports almost all protocols. Here let's choose Shadowsocks as our protocol with which most of us are familiar. Type in the following command in your SSH terminal to install: bash <(curl -L -s https://install.direct/go.sh) Then use your favorite text editor to edit the configuration file located at '/etc/v2ray/config.json'. Here I use vim as my editor and you can use whatever you a...
