Adding PPA repository not working Ubuntu 22.04.4 LTS

[SteveBaker94]

Trying to install MakeHuman...according to your site, the first command I need is:

sudo add-apt-repository ppa:makehuman-official/makehuman-community

...and I get:

Repository: 'deb https://ppa.launchpadcontent.net/makehuman-official/makehuman-community/ubuntu/ jammy main'
Description:
This PPA contains builds of MakeHuman 1.2.x, bundled with community addons (such as MHX). The MakeHuman Community 12x series is a different code branch than the MakeHuman 11x code. The source for MakeHuman and most of the addons can be found at https://github.com/makehumancommunity.

Packages from this PPA should be possible to install and run alongside packages from the makehuman-11x PPA.

To enable the PPA and then install MakeHuman, run:

sudo add-apt-repository ppa:makehuman-official/makehuman-community
sudo apt-get update
sudo apt-get install makehuman-community

On ubuntu this will install all plugins as they are "Recommends" in the packages. If you have switched off "Recommends", or if you are using Mint, you might also want to do:

sudo apt-get install makehuman-community-plugins-socket makehuman-community-plugins-assetdownloader mhx2-makehuman-exchange

This will install some plugins you are likely to want.

For more information, see http://www.makehumancommunity.org

This PPA also contains optional packages. The "makehuman-blendertools" package installs blender integration. The "makehuman-targets-dev", "makehuman-clothes-dev", "makehuman-hair-dev" and "makehuman-bodyparts-dev" contain raw targets and obj files for targets, clothes, hair and body parts respectively. Most people do not need the "*-dev " packages, but if you plan to develop new targets, the "makehuman-targets-dev" might make sense.

If you have questions, ask them on the MakeHuman forum: http://www.makehumancommunity.org/forum

If you need to make a bug report, post it on the MakeHuman bug tracker: http://bugtracker.makehumancommunity.org

First, delete the ppa repository that you have already added, it will not work anyway because there is no version available for your system.
Then, You can use the system's "Software & Updates" graphical application to add the ppa repository again but for the impish version, Ubuntu 21.10 Impish version

deb https://ppa.launchpadcontent.net/makehuman-official/makehuman-community/ubuntu impish main

I don´t really know if it will work, but it will install it
