[FIXED] Chromedriver unexpectedly exited. Status code was: 127 error while running selenium on flask venv

Issue

I am building my first flask app and am having trouble integrating selenium. The app takes an input from an html text field, uses it to pass into a search field with selenium, then runs some code. However, I am getting the following error after entering something into the text field and hitting submit:

An error occurred in get_lyrics: Message: Service /home/vsherr/.cache/selenium/chromedriver/linux64/120.0.6099.109/chromedriver unexpectedly exited. Status code was: 127

An error occurred: Message: Service /home/vsherr/.cache/selenium/chromedriver/linux64/120.0.6099.109/chromedriver unexpectedly exited. Status code was: 127

I have tried upgrading selenium and installing a number of packages, including: pip install -U selenium pip install --upgrade chromedriver-autoinstaller sudo apt-get install -y chromium-browser

What might be causing this?

Edit: I have narrowed it down but still haven't solved the issue. It has to do with chromedriver not working in Ubuntu. Previous solutions have involved editing the filepath to get to the chromedriver. However, this solution has become obsolete as chromedriver no longer requires a filepath.

Solution

I fixed it! Had to do with broken dependencies / installations. Using pip install dependencies solved the first issue. Then I used sudo apt --fix-broken install to fix all this installs. Works perfectly now.
