How to upgrade using the terminal?
-
- First fully update and upgrade your current Ubuntu 20.04 Linux system and also remove all no longer required packages.
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt autoremove
-
- Secondly open and edit the ```
/etc/update-manager/release-upgrades
file and ensure that the <strong>
Prompt
variable</strong> is set to
normal
Open release-upgrades using pico
sudo pico /etc/update-manager/release-upgrades
Edit file release upgrade and change Prompt to normal
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
3. - And the third step is to do a release upgrade
Do release upgrade
sudo do-release-upgrade
<strong>NOTE</strong><br>If you are very close to the release date of Ubuntu 20.10 you may have to use the -d option 'sudo do-release-upgrade -d' in order to begin the upgrade
When the Ubuntu upgrade finishes, reboot the system. Once the system comes up, you'll be running Ubuntu 20.10 Groovy Gorilla Linux as your new system !
