In this section, we’ll tackle the steps needed to fix the ‘client-version’ package errors during a PostgreSQL installation. By following these steps, you’ll clear up any version conflicts and ensure a smooth setup.

Step 1: Identify the Error

First, identify the specific error message in your terminal.

Look closely at the message that pops up when the error occurs. It usually gives you clues about the conflicting versions, which will guide you in fixing the problem.

Using your package manager (like apt or yum), uninstall the older or conflicting versions. This clears the way for a clean installation of the correct package versions.

After that, update your package repository to ensure you have access to the latest versions.

Run sudo apt update or equivalent commands for your operating system. This ensures that when you install PostgreSQL again, you’ll get the most recent, compatible versions.

Step 5: Reinstall PostgreSQL

Finally, reinstall PostgreSQL to resolve the error.

Use your package manager to install PostgreSQL afresh. With the conflicts resolved, the installation should proceed without a hitch.
