Can't for the life of me get seleniumbase to work on Ubuntu

[SebastienBolh]

First off, thank you mdmintz for working so hard on this tool. I tried a million things to fly undetected and nothing worked until seleniumbase with UC mode. The below script is almost straight from the docs, except I duplicated the line sb.uc_gui_click_captcha() a couple times and added logging.

from seleniumbase import SB
import logging

logging.basicConfig(level=logging.DEBUG)

with SB(uc=True) as sb:
    url = "https://gitlab.com/users/sign_in"
    sb.activate_cdp_mode(url)
    sb.uc_gui_click_captcha()
    sb.sleep(2)
    sb.uc_gui_click_captcha()
    sb.sleep(2)

I'll leave out the details of the million things I tried to get my larger project working on Ubuntu, as if I can get this working, I can get everything else working too.

This works fine on mac. I put it on Ubuntu (on prem infra), install all the dependencies (including google-chrome-stable), and run it python3 test3.py.

Expected result: Google chrome opens and we nav to Gitlab, captcha is clicked, captcha is bypassed
Actual result:
Google chrome opens and we nav to Gitlab, then the DEBUG dump output.txt.

I can't tell whats wrong and I'm not sure where to look to debug or fix it.

Do you know whats wrong? Do you need more information?

Thank you,

• Seb

For the X11 display failed!, that's a duplicate of #3404, #3060, and #2982.

Check the following to find out if your Linux distribution is missing X11 display dependencies:

When everything is configured properly on Ubuntu, things work. Eg:

(GitHub Actions Ubuntu machines come with the X11 display dependencies.)

@mdmintz Thank you for the prompt reply. I read those issues and the links you sent.

After installing a bunch of different packages, especially xvfb, and adding headed=True (after xvfb installation it seems to default to headless) to the script:

from seleniumbase import SB
import logging

logging.basicConfig(level=logging.DEBUG)

with SB(uc=True, headed=True) as sb:
    url = "https://gitlab.com/users/sign_in"
    sb.activate_cdp_mode(url)
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()

I've added sleeps in between with the same results.

The website opens, the cloudflare turnstyle appears, then there does not seem to be any click action, instead I get this
output.txt. This is on a fresh Ubuntu instance on xorg, google-chrome is installed and never opened (besides by seleniumbase).

I read the whole output.txt and I don't see anything I can recognize as a problem.

Any idea what I could be missing here?

Worth noting if I use Driver:

from seleniumbase import Driver
import logging

logging.basicConfig(level=logging.DEBUG)

with Driver(uc=True, headed=True) as sb:
    url = "https://gitlab.com/users/sign_in"
    sb.uc_open_with_reconnect(url)
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()
    sb.uc_gui_click_captcha()

The only new behavior is that now it automatically attempts to refresh the page. But it still won't click the turnstyle.

The output is as such: outputDriver.txt

It's probably related to PyAutoGUI on Linux:
https://github.com/search?q=repo%3Aasweigart%2Fpyautogui+linux&type=issues
It's working fine on my Linux machine, so you should probably check out the troubleshooting from the PyAutoGUI repo directly.
