for my college work I need to set up a DHCP server on a ubuntu vm. I am connected via a vpn to the school network and accessed it through Putty. Everything works as planned but when I try to run sudo apt-get install isc-dhcp-server i get the following error message:
What seems to be the problem here?
I normally use Windows so Ubuntu is very new to me.
If anyone could give me some advice or maybe explain what the problem is, it would be very much appreciated
