Before upgrading to a newer Ubuntu release, it’s essential to install all available updates for your current version. This ensures a smoother upgrade process and reduces the chances of encountering issues during the upgrade.
In this tutorial, we’ll show you how to install all available updates for your current Ubuntu release before upgrading.
Step 1: Update the Package List
Open a terminal window and run the following command to update the package list:
sudo apt update
This command fetches the latest package information from the configured repositories and updates the local package list.
Step 2: Install Available Updates
Now that the package list is updated, install all available updates with the following command:
sudo apt upgrade
The command above will prompt you to confirm the installation of updates. Press ‘Y’ and then Enter to continue with the installation.
After the updates are installed, it’s a good idea to also run the following command to perform a more thorough upgrade that handles package dependencies more carefully:
sudo apt dist-upgrade
Again, you will be prompted to confirm the installation of updates. Press ‘Y’ and then Enter to proceed.
Step 3: Clean Up Unused Packages
After updating your system, it’s a good practice to clean up any unused or obsolete packages. You can do this by running the following command:
sudo apt autoremove
Step 4: Reboot Your System
Once all updates are installed and the system is cleaned up, it’s recommended to reboot your system to ensure that any changes take effect:
sudo reboot
Step 5: Upgrade to the New Ubuntu Release
After completing the steps above, your system should be up-to-date with the latest packages for your current Ubuntu release. You can now proceed with upgrading to the new Ubuntu release using the following commands:
First, install the update manager core package if it’s not already installed:
sudo apt install update-manager-core
Next, start the upgrade process by running:
sudo do-release-upgrade
Follow the on-screen instructions to complete the upgrade process. The system may prompt you several times to confirm the installation of packages or the removal of obsolete ones.
