The error message "Unable to establish a connection to security.ubuntu.com:80" keeps popping up while attempting to execute a shell command in Databricks

I have been trying to implement Selenium on an AWS Databricks platform following the guidelines in a recent post. However, every time I execute the code provided, I encounter the same error:

Partial Error:

Could not connect to security.ubuntu.com:80

Code:

%sh
/dbfs/databricks/scripts/selenium-install.sh

The complete error details are listed at the end of this post. I have checked the Network ACLs and Security Groups in my AWS account, which seem to allow HTTP(80) ports for inbound and outbound traffic, but since I am not well-versed with AWS, I might be missing something. To troubleshoot, I even added a new Security Group for Outbound 80 access without success. Any guidance in troubleshooting this issue would be greatly appreciated.

I also tried running the suggested code mentioned in the full error message, but encountered similar connection errors:

Suggested Code:

%sh
sudo apt-get update

Answer №1

After further investigation, it appears that the problem lies within the outbound access controls of our firewall system, which are responsible for managing user permissions and regulating network configurations for our AWS platform services. Initially, only port 443 (HTTPS) and MySQL were permitted for access. However, we realized that in order to facilitate the execution of certain commands via HTTP, it was necessary to include port 80 as well.
