How to update Ubuntu

Also, before upgrading to any latest Ubuntu version, one should also update current packages that are installed if new versions are available.

If you have packages held back for any reason, you may want to release the hold and maybe upgrade to the latest version. Run the commands below to show any packages being held back from upgrade.

sudo apt-mark showhold

To release the hold, run the commands below, replacing package_name with the name of the package being held back.

sudo apt-mark unhold package_name

Next, run the commands below to update all current packages currently installed.

sudo apt update
sudo apt upgrade

Next, run the commands below to perform full upgrade so that packages which may prevent your machine from upgrading are removed.

sudo apt full-upgrade
sudo apt --purge autoremove

Upgrade to Ubuntu 22.04

Now that your system has been updated and rebooted, you can now start upgrading to the latest version of Ubuntu.

Ubuntu comes with an upgrade package called “update-manager-core” which is installed by default on both desktops and servers. If it’s not already installed, you can run the commands below to do so.

sudo apt install update-manager-core

Once the package is installed, make sure that the default upgrade policy in the /etc/update-manager/release-upgrades file is set to “Prompt=normal” or “Prompt=lts”.

If the option is set to lts but still unable to upgrade, change to normal and try again.

Finally, run the commands below to start the upgrade process

sudo do-release-upgrade

During the upgrade process you’ll be prompted and asked various questions, like whether you want to keep an existing configuration file or to install the package maintainer’s version.

In most cases if you haven’t done lots of custom configurations, you can safely type Y for Yes.

Wait for the upgrade process to complete. Once the process is done, you’ll be prompted to reboot.

After rebooting, run the commands below to verify that your Ubuntu system was upgraded.

lsb_release -a

You should see something similar to the lines below:

No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 22.04 LTS
Release:	22.04
Codename:	jammy
