This error message usually occurs when trying to run a graphical application or program on a local machine with X11 forwarding enabled, but the display server is not set up properly.
To solve this issue, you can try the following steps:
1. Check if the X11 server is running on your local machine by running the following command in a terminal:
```
ps -ef | grep Xorg
```
If the X11 server is not running, you can start it by running the following command:
```
sudo service lightdm start
```
2. Make sure that the DISPLAY environment variable is set correctly. You can check the current value of the DISPLAY variable by running the following command:
```
echo $DISPLAY
```
If the value is not set or set incorrectly, you can set it manually by running the following command:
```
export DISPLAY=:0
```
3. If you are still encountering the same error message, try disabling any firewall or security software that may be blocking the X11 connection.
If none of these steps work, you may need to consult the documentation or support forums for the specific application or program you are trying to run.
