    21.10 has reached the end of life (EOL). It's repositories have been archived. As the repositories are not there, `apt` cannot download `Ubuntu-desktop`. Questions about EOL versions of Ubuntu are off topic here. – user68186 May 20 '23 at 16:35

    Does this answer your question? [How to install software or upgrade from an old unsupported release?](https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release) – nobody May 20 '23 at 16:38
  • The way people answer questions on here is so condescending. It’s obvious I know how to type case sensitive command line prompts. The problem is not the case sensitivity otherwise it would have given a different error (duh). If you can’t help and don’t know how to resolve the problem, don’t be a jerk – Mar Mustafa May 20 '23 at 17:46

    At this point, this version of ubuntu is not anymore supported. Download Ubuntu 22.04 (supported until April 2027), and write it to a live USB. You can perform backup of any necessary files from the live environment, and then perform a fresh installation of Ubuntu 22.04. – Archisman Panigrahi May 20 '23 at 18:07

Ubuntu 21.10 (Impish Indri) End of Life reached on July 14 2022.

Ubuntu 21.10 is no longer supported. It is archived to old-releases.ubuntu.com. You have edit /etc/apt/sources.list and change 'archive.ubuntu.com' to 'old-releases.ubuntu.com'.

This can be done by typing

sudo sed -i -e 's/archive.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

in the terminal. After running this command, run sudo apt update && Sudo apt install ubuntu-desktop. It is best you update to a newer and supported version of Ubuntu unless you have a very specific and genuine reason to stay on Ubuntu 21.10.

If you are trapped you can try installing an alternative DE like cinnamon or KDE. To install KDE use the following command

sudo apt install kde-plasma-desktop

or you can upgrade your desktop using the command

sudo do-release-upgrade

Hope this helps you.
