Upgrade Ubuntu to 20.10 Groovy

Requirements

System : Ubuntu: 20.04 Focal Fossa and privileged access to your Linux system as root or via the sudo command.

Note: Please upgrade your ubuntu to 20.x.x if your current version is lower than 20.x.x!

Step: 1

Update and upgrade your current packages

$ sudo apt update 
$ sudo apt upgrade
$ sudo apt dist-upgrade

Step: 2

Remove all your unwanted packages

$ sudo apt autoremove

Step: 3

Make sure to change your prompt variable to normal

$ sudo vim /etc/update-manager/release-upgrades

Open it in your editor, you can see a file like this

# Default behavior for the release upgrader.

[DEFAULT]
# Default prompting behavior, valid options:
#
#  never  - Never check for 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 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 this option should not be
#           used if the currently-running release is not itself an LTS
#           release, since in that case the upgrader won't be able to
#           determine if a newer release is available.
Prompt=normal

Step: 4

Begin the upgrade by

$ sudo do-release-upgrade

Step: 5

Reboot your system

$ sudo reboot

Enjoy the new Groovy! Thank you
