I have a raspberry pi which is connected to University network via wi-fi. I usually just ssh to it through my PC if i want to do anything. The internet is working as I can ping google and even fetch data from the internet using basic commands. However, when I try to perform apt-get update, the following error pops-up
My understanding is that there is some sort of required authentication that I do not know about. It works fine at home if anything. My question is if there's anything that can be done to get rid of this error?? Please help
