Try launching chromium from the command line and see what happens (make sure it's the same one your script is using). That error just means chrome/chromium failed to launch (for whatever reason). We really need to get chromedriver to return a better error message, because that message is returned whenever any internal error occurs and it's misleading and useless. Also, please post the code you are using (your pastebin just shows the script you called it with) |

@cgoldberg The code that now i try to run is a simple one (ignore the import library because i copied from an other code): |

This is not a Selenium-specific issue. @cgoldberg is being very kind in helping out. Please try and see this thread too #15327. In case you find some useful suggestions. |

@FJSF so yea... that's the issue. If you can't launch chrome on that system, there's no way selenium can launch it. I'm going to close this, since it's a chrome/chromium issue. You can try reporting it to chromium developers to figure out why it won't launch. |

What happened?
Hi, i am currently trying to run a python script that navigate on the web with selenium and get the html of the product page on a web site and then do scraping to collect info. The info are stored in a database mariadb.
I am on a Rasberry pi 5 on Ubuntu, the version of Chromium is Chromium 133.0.6943.141 snap and the version of the chromedriver is ChromeDriver 133.0.6943.141 (2a5d6da0d6165d7b107502095a937fe7704fcef6-refs/branch-heads/6943@{#1912}). As the title said i can't run the script without getting the error:
My chrome options are:
options = Options()
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--headless=new')
options.add_argument('--disable-gpu')
options.add_argument('--disable-extensions')
options.add_argument('--remote-debugging-port=9222') # Specify a port
options.add_argument('--disable-setuid-sandbox')
options.add_argument("--incognito")
options.add_argument("--disable-application-cache")
options.add_argument("--enable-do-not-track")
options.add_argument("--disable-popup-blocking")
options.binary_location = '/snap/bin/chromium'
service = Service('/usr/bin/chromedriver')
I saw in a github report that maybe there is a problem when running as root, i checked and i am not running as root, i tried to run the chromedriver and:
so i checked with
ps -aux | grepchromedriver and i got:then i tried to run the same command to check with chromium before i could get the error and:
I lost hope.
ps: i have a pastebin with the code: https://pastebin.com/aL4QiGV4 (dont read the message README because is from another error with cron)
How can we reproduce the issue?
