After changing the installation of the driver and adding the installation of chrome itself

following this
https://gist.github.com/ziadoz/3e8ab7e944d02fe872c3454d17af31a5

i managed to get rid of the error… now the crawler stays silent for a minute attempting to start the driver and then dies like this:

root@my:/var/crawlers# python3 munchery_spider.py
starting driver…
Traceback (most recent call last):
