How to Back up Ubuntu
Before upgrading Ubuntu, your first task should be to take a backup of your current system so you can restore if something unexpected happens when upgrading.
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
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.
