I am unable to run the command sudo apt install ros-foxy-desktop. Following the guide here: . I am able to complete all the steps until the final install which gives these errors.
Any help would be much appreciated. I've already tried to install by the guide here . Is it because I am running ubuntu 21.10 desktop and need to be running 20.04 server? The issue I run into with the 20.04 server is that I won't be able to connect to the university I am at wifi, the wifi uses PEAP and I don't know how to set that up with the server to connect to the wifi.

Currently Foxy is build for 20.04 and as such there is not a 21.04 release you can install. You will either have to install 20.04 or run some sort of container(i.e. docker).
As for the PEAP authentication, I would potentially look at this askubuntu thread.
