Selenium Base does not work on a stock ubuntu droplet instance

[zackees]

Ubuntu 24.10
Image: s-2vcpu-4gb, but any will probably work with enough ram

Install:

apt install -y python3 python3-pip
pip install uv --break-system-packages
uv venv
uv pip install seleniumbase

Then I paste this script in

from seleniumbase import BaseCase
BaseCase.main(__name__, __file__)  # Call pytest

class MyTestClass(BaseCase):
    def test_swag_labs(self):
        self.open("https://www.saucedemo.com")
        self.type("#user-name", "standard_user")
        self.type("#password", "secret_sauce\n")
        self.assert_element("div.inventory_list")
        self.click('button[name*="backpack"]')
        self.click("#shopping_cart_container a")
        self.assert_text("Backpack", "div.cart_item")
        self.click("button#checkout")
        self.type("input#first-name", "SeleniumBase")
        self.type("input#last-name", "Automation")
        self.type("input#postal-code", "77123")
        self.click("input#continue")
        self.click("button#finish")
        self.assert_text("Thank you for your order!")

This is the output I get back:

Most likely this can be fixed with a helpful error message. It's on a worker machine and remote debugging isn't easy.

Can anyone help me figure out a work around? I'm guessing it's probably the binary failing to start. Process failure message seems to be swallowed up.

Devs, can you insert a warning with whatever subprocess.run was streaming?

Looks like a duplicate of SeleniumHQ/selenium#14609 for your custom Ubuntu instance.
Regular Ubuntu Linux is working fine for me, eg:
https://github.com/seleniumbase/SeleniumBase/actions/runs/12779997552).
For your custom "stock ubuntu droplet instance", there's nothing I can do from my end unless there's a change on the https://github.com/SeleniumHQ/selenium side.
