To Owner - Is the uc_driver provided compatible with arm 64 architecture?

[shreyash-work-fl]

Hi,
I stumbled across this great library day before yesterday, and it has been solving issues that I faced in other automation libraries. The problem I am facing now is when I tried deploying it on my ubuntu server, it is giving me an error -

OSError: [Errno 8] Exec format error: '/home/ubuntu/SeleniumBase/SeleniumBase/seleniumbase/drivers/uc_driver'

I have checked the web and I am not sure where the problem lies. It has all the file permissions. So I just wanted to ask you if the uc_driver that comes with the library compatible with the arm 64 architecture? If not, is there any workaround?

Thank You.

Hello, SeleniumBase is compatible with ARM 64 architecture. Verified on my M2 Mac, and also on GitHub Actions running UC Mode on Ubuntu systems. See: https://github.com/mdmintz/undetected-testing/actions/runs/5932953380

Your error looks to be caused by missing #!/bin/sh in at least one of your shell scripts. See https://stackoverflow.com/a/27608363/7058266 for details.

Hello Michael,

I came across the smiliar issue with aarch64 Linux, though it worked find on all my Apple Silicon Macs. The the seleniumbase project was fully developed on an M1 Pro Mac
uname -a

Linux usarm 6.1.0-35-arm64 #1 SMP Debian 6.1.137-1 (2025-05-07) aarch64 GNU/Linux

uname -r

6.1.0-35-arm64

sbase get chromedriver latest

file /root/miniconda3/envs/amazon/lib/python3.9/site-packages/seleniumbase/drivers/chromedriver
/root/miniconda3/envs/amazon/lib/python3.9/site-packages/seleniumbase/drivers/chromedriver: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=42432337a91f9dc908c4ae8e6cf7daa31f730bee, stripped

and of course running /path/to/chromedriver returned chromedriver: cannot execute binary file: Exec format error

I am running with the latest seleniumbase on Debian 12. Any clue why this it? thank you in advance!

Seems because googlechromelabs does not have official support for Linux Arm64.

You’ll probably want Ubuntu (not Debian) if using Linux.

Alright, i've done a quick dd to ubuntu 25.04 but sbase still can't identify and install the correct arch chromdriver.

[sarkrui]

Alright my workaround is to install snap install chromium and then apt install chromium-chromedriver and copy chromedriver to the environment directory. cp /usr/lib/chromium-browser/chromedriver /root/miniconda3/envs/test/lib/python3.9/site-packages/seleniumbase/drivers/

I would observe the GitHub Actions examples on Ubuntu for proper use: https://github.com/mdmintz/undetected-testing/actions/runs/15655938351/job/44107012860
Also, chromedriver isn’t meant to be called directly. It should be used via SeleniumBase scripts.
