how do you fix the executable error with chromedriver Windows >>> in a transition to Ubuntu?

My goal is to execute a script i've used previously on windows, transitioned to chromedriver and there's this error:

Blockquote selenium.common.exceptions.WebDriverException: >> Message: 'chromedriver' executable needs to be in the PATH.

the windows exe file is in the PATH and works with windows. I've replaced that chromedriver with an up to date version of Linux chromedriver, have installed chrome web browser to the default directory. it seems to not recognize that the file is there and in the code it's not specified that it's a .exe it's looking for.

Here is the code

        self.curr = self.conn.cursor(buffered=True)
        self.curr.execute("""create table IF NOT EXISTS auction_tb(

            last_id = self.curr.fetchone()
            self.id_no = last_id[0]
        except:
            self.id_no = 0
        f = open("/opt/lampp/htdocs/scrapy/result.txt", "w")
        f.write("scraping")
        f.close()

in the code i've changed the driver directory to match ubuntu (change xampp to lampp and the directories prior) and i've added a placeholder for the website scraping. This part of the script and the whole script runs on windows perfectly. things i've tried:

1. replacing the .exe file with the equivalent linux file.
2. loading wine of the computer to execute the .exe when it's called. some things about that... after installing wine i right clicked the executable to open it with wine and wine was not an available option and there was no availability to search the computer for it.
3. I have seen and tried the linux server options from here How to implement chromedriver in selenium in Linux platform
4. scrolling down 3/4 down this page they've coded in Javascript something that apparently works for java.. here i'm unsure how to edit my python code in a similar way.https://tecadmin.net/setup-selenium-chromedriver-on-ubuntu/
5. I change the pathing and do research but mostly i think the problem here is that i don't know how to change my code to make it work for linux.
