Upgrade Ubuntu to 22.04/22.10

  1. Upgrade distro
    sudo apt-get dist-upgrade
  2. Upgrade Ubuntu to the latest LTS release

    Run the following command until you get your Ubuntu to version 22.04:

    sudo do-release-upgrade
  3. Change default branch from lts to normal

    Once you update your Ubuntu to 22.04, the latest LTS version, you need to tell the update manager to get the newest short-term supported Ubuntu 22.10.

    sudo sed -i 's/lts/normal/g' /etc/update-manager/release-upgrades
  4. Change default distro from your current
    • 20.04 - focal
    • 20.10 - groovy
    • 21.04 - hirsute
    • 21.10 - impish
    • 22.04 - jammy
    • 22.10 - kinetic (development branch)

    in the example below, we are upgrading from Ubuntu 22.04 (jammy) to 22.10 (kinetic)

    sudo sed -i `s/jammy/kinetic/g` /etc/apt/sources.list
  5. Update packages list
    sudo apt-get update
  6. Upgrade packages
    sudo apt-get upgrade
  7. Run full upgrade
    sudo apt-get dist-upgrade
  8. If any error re-run
    sudo apt-get update
    sudo apt-get dist-upgrade
  9. Run cleanup
    sudo apt-get autoremove
    sudo apt-get clean
  10. Reboot the system
    sudo shutdown -r now

Upgrade Ubuntu kernel version

  1. Change current directory to /tmp
    cd /tmp
  2. Download latest stable kernel
  3. Install latest stable kernel
    sudo dpkg -i *.deb
  4. Reboot system after latest stable kernel upgrade
    sudo shutdown -r now
  5. Change current directory to /tmp
    cd /tmp
  6. Download latest mainline kernel (optionally)
    If you experience some issues with the latest stable kernel or want to test the newest release candidate you might give the latest kernel release candidate a try. But be cautious, it is still in development, and while fixing some bugs, new ones might appear. There are two ways to install latest mainline kernel:
    • sudo add-apt-repository ppa:cappelikan/ppa -y
    • sudo apt-get update
    • sudo apt install mainline -y
    or:
  7. Install latest mainline kernel
    sudo dpkg -i *.deb
  8. Reboot system after latest mainline kernel upgrade
    sudo shutdown -r now

Finishing up

  1. Update packages list
    sudo apt-get update

  3. Reboot the system if needed
    sudo reboot
