Comment 2 for bug 1836236

This command was reported to successfully work around this bug:

  sudo sed -i 's/^Automatically/# Automatically/g' /var/lib/dpkg/info/base-files.postinst

It changes any lines starting with "Automatically" into comments, which lets the script finish properly when you run:

  sudo dpkg --configure base-files

Or just run this afterwards:

  sudo apt -f install
