I was trying to run some Selenium tests in Docker. I moved from ubuntu:bionic to bitnami:jessie and I found that chromium-browser is available in bionic and chromium is available in jessie.
what is the difference between these two packages? if i install chromium, then I get following error when running Protractor tests.

What is your chromium version?
Here you can see similar problem: Chromedriver Devtools port number error
Right now you are using chromedriver 2.46.628388. It supports chrome v71-v73 (http://chromedriver.chromium.org/downloads)
If your chromedriver is older:
a) update it or,
b) downgrade chromedriver
