Fix Plan

To prevent overwriting of the existing ollama.service file, we need to modify the installer script to check for the file's existence and prompt the user for confirmation before overwriting it.

Steps to Fix

• Modify the installer script to include a check for the existence of /etc/systemd/system/ollama.service
• Add a confirmation prompt to ask the user if they want to overwrite the existing file
• Use a flag to skip overwriting the file if the user chooses not to overwrite it

Example Code

if [ -f "/etc/systemd/system/ollama.service" ]; then
  read -p "The file /etc/systemd/system/ollama.service already exists. Do you want to overwrite it? (y/n) " -n 1 -r
  echo
  if [[ $REPLY =~ ^[Nn]$ ]]; then
    echo "Skipping overwrite of /etc/systemd/system/ollama.service"
    # skip overwriting the file
  else
    # overwrite the file
    cp new_ollama.service /etc/systemd/system/ollama.service
  fi
else
  # file does not exist, overwrite it
  cp new_ollama.service /etc/systemd/system/ollama.service
fi

Verification

After applying the fix, run the installer again and verify that it prompts for confirmation before overwriting the existing ollama.service file. If the user chooses not to overwrite the file, verify that the file is not modified.

Extra Tips

• Make sure to test the installer script thoroughly after applying the fix to ensure it works as expected in different scenarios.
• Consider adding a flag to the installer script to force overwrite of the file without prompting the user, for automated installations or other use cases where confirmation is not required.
