Download and install Ubuntu 22.10 ‘Kinetic Kudu’. How to Upgrade to Ubuntu 22.10 from Ubuntu 22.04. Update to Ubuntu 22.10 ‘Kinetic Kudu’
Method 1
To upgrade on a desktop system:
- Open the “Software & Updates” Setting in System Settings.
- Select the 3rd Tab called “Updates”.
- Set the “Notify me of a new Ubuntu version” drop down menu to “For long-term support versions” or “For any new version”.
- Press Alt+F2 and type update-manager -c -d into the command box.
- Update Manager should open up and tell you that Ubuntu 22.10 is now available.
- If not you can run /usr/lib/ubuntu-release-upgrader/check-new-release-gtk
- Click Upgrade and follow the on-screen instructions.
To upgrade on a server system:
- Install update-manager-core if it is not already installed.
- Make sure the Prompt line in /etc/update-manager/release-upgrades is set to ‘normal’ if you want non-LTS upgrades, or ‘lts’ if you only want LTS upgrades.
- Launch the upgrade tool with the command sudo do-release-upgrade -d
- Follow the on-screen instructions.
Note that the server upgrade will use GNU screen and automatically re-attach in case of dropped connection problems.
There are no offline upgrade options for Ubuntu Desktop and Ubuntu Server. Please ensure you have network connectivity to one of the official mirrors or to a locally accessible mirror and follow the instructions above.
Method 2
First of all, check for a new stable Ubuntu release using this command:
$ sudo do-release-upgrade -c
Now make the necessary changes to search and download the new Ubuntu version (other than LTS). Use the following command:
$ sudo nano /etc/update-manager/release-upgrades
Here, set Prompt=normal in the file /etc/update-manager/release-upgrades. Note that it is set to Prompt=lts by default. Once done, save the changes by pressing Ctrl + O and then exit the editor by pressing Ctrl + X.
Now, run the following set of commands and follow on-screen instructions to upgrade to Ubuntu 22.10:
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install update-manager-core
$ sudo do-release-upgrade -d
$ sudo apt update && apt upgrade
After the installation is complete, remove previously pre-installed software which is no longer included in the latest release. Run the following command:
$ sudo apt autoremove --purge
