How to fix unmet dependencies for udev:amd64 error on Ubuntu 18.04?
I was able to fix this by forcibly overwriting /var/cache/apt/archives/udev_237-3ubuntu10.9_amd64.deb
sudo dpkg -i --force-overwrite /var/cache/apt/archives/udev_237-3ubuntu10.9_amd64.deb sudo apt purge udev sudo apt-get update sudo apt-get upgrade
