It's time to say goodbye to the Ubuntu 20.10 "Groovy Gorilla" operating system as it reached support end on July 22, 2021.
As announced some time ago by Ubuntu maker Canonical, Ubuntu 20.10 Groovy Gorilla will not be supported with software updates and better safetys from July 22, 2021. This means that if you are using Ubuntu 20.10, you should seriously consider upgrading to a newer version as soon as possible.
Ubuntu 20.10 was released nine months ago on October 22, 2020 and was the first version of the Raspberry Pi 4 operating system. It used the Linux 5.8 kernel and by default had the GNOME 3.38 desktop environment.
But because it wasn't an LTS release (Long-Term Support Support), Ubuntu 20.10 could only be updated for nine months, until July 22, 2021. After that date, Canonical stopped providing updates for Groovy Gorilla, which, over time, will become vulnerable to all sorts of attacks.
On July 21, 2021, Canonical released the latest security update for Ubuntu 20.10 (Groovy Gorilla), so if you continue to use the distribution for a few more days or weeks until you are ready to upgrade to Ubuntu 21.04, you should be safe . However you should consider considering an upgrade as soon as possible.
Before proceeding with upgrading to Ubuntu 21.04 (Hirsute hippo), which has a newer kernel for better hardware support (Linux 5.11), and support for applications GNOME 40 and Wayland by default, it would be a good idea to take a backup.
Ubuntu 21.04 will be supported for another six months, until the end of January 2022, but Canonical will release Ubuntu 21.10 (Impish Indri) on October 14, 2021, with the latest GNOME series in version 40 by default, Linux 5.14 kernel and many other improvements.
