When trying to change default search engine in chrome to duckduckgo, it's not on the dropdown (settings > search engine). Copying the search url to 'site search' doesn't work, ddg not listed on search engine and cannot be made default.
Google search on how to change to ddg produces old results that don't apply to the status quo. I still haven't figured out how to do it. I don't want to install the extension or use the ddg browser.
This is using the .deb file from google, on ubuntu LTS. As vanilla a chrome install as it can be.
Google seems to be going heavy-handed on people staying with their search engine.
Or maybe try one of the any Chrome derivatives that may have less dark patterns like De-googled Chromium or even Brave?
