Other base system changes since 18.04 LTS

Python3 by default

In 20.04 LTS, the python included in the base system is Python 3.8. Python 2.7 has been moved to universe and is not included by default in any new installs.

Remaining packages in Ubuntu which require Python 2.7 have been updated to use /usr/bin/python2 as their interpreter, and /usr/bin/python is not present by default on any new installs. On systems upgraded from previous releases, /usr/bin/python will continue to point to python2 for compatibility. Users who require /usr/bin/python for compatibility on newly-installed systems are encouraged to install the python-is-python3 package, for a /usr/bin/python pointing to python3 instead.

Snap Store

The Snap Store (snap-store) replaces ubuntu-software as the default tool for finding and installing packages and snaps.

Ubuntu comes with everything you need to run your organization, school, home or enterprise. All the essential applications, like an office suite, browsers, email and media apps come pre-installed and thousands more games and applications are available in the Ubuntu software centre.

Open source
Ubuntu has always been free to download, use and share. We believe in the power of open source software; Ubuntu could not exist without its worldwide community of voluntary developers.

Secure
With a built-in firewall and virus protection software, Ubuntu is one of the most secure operating systems around. And the Long Term Support releases give you five years of security patches and updates.

Accessible
Computing is for everyone regardless of nationality, gender or disability. Ubuntu is fully translated into over 40 languages and includes essential assistive technologies.

Looks great on the latest hardware
Ubuntu is designed to work beautifully on the latest laptops, desktops and touch screen devices, it looks incredible on high resolution screens — and with touch screen enhancements and interface refinements including individual menu bars in each application window, it’s now even easier to use.
