Encountering a glitch upon launching Selenium with chromedriver on Debian 8

I am attempting to utilize Selenium with Google Chrome. It is functioning perfectly on my personal computer, but I am encountering issues when trying to run it on my Debian 8 64-bit server. The following error message appears:

root@vps:/opt/SupportBot# java -jar /opt/web/googletest.jar
Starting ChromeDriver 2.34.522913 (36222509aa6e819815938cbf2709b4849735537c) on port 14684
Only local connections are allowed.

The code I am using for both my Windows PC and Debian 8 server can be found here: https://pastebin.com/auyNbi28

Software Used: - Selenium version 3.8.1 - ChromeDriver 2.34 - Debian 8

Update: With C-Otto's help, I have made progress! I discovered that the issue was due to Chrome not being installed. However, I am now encountering this error repeatedly:

Starting ChromeDriver 2.34.522913 (36222509aa6e819815938cbf2709b4849735537c) on port 2783 Only local connections are allowed. [0.748][SEVERE]: CreatePlatformSocket() returned an error, errno=97: Address family not supported by protocol (97)

Answer №1

The initial issue that you encountered was :

sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

This error could be due to any of the following reasons :

  • java.lang.RuntimeException: exception in constructor
  • java.lang.reflect.InvocationTargetException
  • java.lang.IllegalArgumentException

You can explore a detailed discussion on these points in this Answer.

The second issue you were facing is :

[SEVERE]: CreatePlatformSocket() returned an error, errno=97: Address family not supported by protocol (97)

Mis-configuration in the /etc/hosts file is often the reason for this error. Verify that the entries in /etc/hosts are correct as shown below :

....
---   127.0.0.1       localhost.domain               localhost
+++   127.0.0.1       localhost               localhost

Typically, CreatePlatformSocket() errors stem from IPv6 probing in host_resolver_impl.cc.

Issue#700347 clearly states that Chrome doesn't support Linux kernels without IPv6 support. Refer to a list of supported Linux distributions under See system requirements here: https://support.google.com/chrome/answer/95346?hl=en&ref_topic=3227046

This crash has been reported to Chromium and is being monitored here.
