I am a new user to Ubuntu 22.04 as a Guest OS inside VM VirtualBox v6.1. And this is my first Ubuntu question in this forum.
I have been trying to install the rest2web package but no matter what my effort, the package installer says the package rest2web was not found. (Even including the full URL to the package download page, but still not found.) I am not sure if I am supposed to use pip3 or else apt-get, have tried both without success.
Another package, Noetic Ninjemys (ros-noetic-desktop-full) caused me similar problems being also not found, but I am told there are trusted keys involved with apt-key deprecated.

Updating from such a repository cannot be done securely and is therefore disabled by default." When I tried entering some other repositories there, they were not retained (saved).
I hope you can assist with these package install difficulties. Thank you.
