Upgrade Xubuntu 18.04 to 20.04

Question

Is there any option to update Xubuntu 18.04.4 LTS to Xubuntu 20.04 from terminal.

I tried with sudo apt update && sudo apt upgrade but I think that i did just apt update without upgrade.

Solution 1

I would always recommend reading the release notes for the release you are wanting to move to, for Xubuntu the release notes are

https://wiki.xubuntu.org/releases/20.04/release-notes#updates

They however do not have Xubuntu specific release upgrade notes, they instead refer you to the Ubuntu 20.04 release notes which are

https://wiki.ubuntu.com/FocalFossa/ReleaseNotes

which includes the terminal command (see upgrading servers)

sudo do-release-upgrade -d

but I'd recommend you read the release notes first, rather than copy/paste this command into your system (starting with the Xubuntu notes first). Release notes include a list of known issues which were encountered by testers of the system providing warning of issues you may encounter.

If you're willing to wait, you will be offered the opportunity to upgrade your system (with fewer issues expected) after the upgrade path is normally opened a few days after the Xubuntu 20.04.1 official release.

Solution 2

apt update

is used to check and update your package repository for new versions of your installed packages.

apt upgrade

is used to "update" those packages to their new versions.

Here is a website that describes the process of manually upgrading to a new distro-release via GUI or command-line

Does this answer your question? Is the "Final Release" a "Development Release"?

The release notes you provided are a list of 50 programs each having their own release notes.

@NicholasBourbaki I don't understand your point or question. The link I gave was the official release notes, which yes contain links to many programs, and in fact many products (including official flavors, and some unofficial but affiliated products from other companies related to cloud etc). The official release notes link elsewhere where more specific advice is available (they'd be too long if all details, for all applications, images & flavors (plus their programs etc) were included). We tend to trim/add to our initial install, so our systems tend to be unique so we can read what applies
