Steps to Upgrade Ubuntu To 21.10 Impish Indri using commands

Please keep in mind that you can only update to Ubuntu 21.10 from the Ubuntu 21.04 version. As a result, if you want to upgrade from Ubuntu 20.04 or 20.10, you must first update to Ubuntu 21.04. When you’re ready, you can start the Ubuntu 21.10 upgrade process.

To Upgrade Ubuntu to 21.10 from 21.04, you need:

  1. To begin, make sure your Ubuntu 21.04 Linux system is updated. Run the following commands:
    $ sudo apt update
    $ sudo apt upgrade
    $ sudo apt dist-upgrade
  2. Configure the release upgrader. To adjust the release upgrader, you must open /etc/update-manager/release-upgrades file, and change file same as below:
    # Default behavior for the release upgrader.
    # Default prompting and upgrade behavior, valid options:
    #  never  - Never check for, or allow upgrading to, a new release.
    #  normal - Check to see if a new release is available.  If more than one new
    #           release is found, the release upgrader will attempt to upgrade to
    #           the supported release that immediately succeeds the
    #           currently-running release.
    #  lts    - Check to see if a new LTS release is available.  The upgrader
    #           will attempt to upgrade to the first LTS release available after
    #           the currently-running one.  Note that if this option is used and
    #           the currently-running release is not itself an LTS release the
    #           upgrader will assume prompt was meant to be normal.
