Based on the error message, it seems that there is an issue with the proxy settings and port usage. The warning indicates that the connection is using a proxy that may not be intended, so you may want to check your proxy settings and adjust them accordingly.
The error message suggests that Port 10250 is already in use, which could potentially cause issues with the installation process. You can try stopping any processes or services that might be using this port before running the installation again.
If you are familiar with Kubernetes and know what you are doing, you can also ignore preflight errors by using the --ignore-preflight-errors flag. However, this should only be done if you understand the implications of ignoring these errors.
To get more information about the error and see a stack trace, you can run the command with the --v=5 or higher flag. This will provide more detailed output about what went wrong during the installation process.
